professor what are fractions and how do I multiply them?? I moved schools at third grade, my first school taught them in 4th and the second school caught them in 3rd so I never actually learned them

-very confused critter

Fractions

Fractions are parts of a whole. To put it simply, imagine a pizza, divide it into 8, then you have 8/8 parts. Take 1 part away, and you have 7/8 of the pizza left. So on, so forth.

Fractions can also be seen as division.

More explanation can be seen under the cut.

Parts of a Fraction

Normal fractions are written like this:

Or, as I had written earlier: 8/8.

As mentioned, fractions are also division. 8 is being divided by 8. The denominator is the divisor, and the numerator is the dividend.

Whole Numbers, Improper Fractions, & Proper Fractions

8/8 = 1, because if you divide 8 by 8, you get the quotient of 1. Same with other numbers. 3/3 = 1. Now, imagine we have 16/8. That's basically 16 divided by 8, which is 2.

Improper fractions are fractions where the numerator is greater than the denominator. Such as 9/8. What do we do if we have 9/8? Obviously, we cannot easily divide 9 by 8. Well, if you recall the lesson of remainders during division, that is what we do here.

To turn a proper fraction into an improper fraction, we simply multiply the denominator by the whole number & add the value with the numerator.

Whole numbers can also be turned into decimals. 1/1 = 1, 2/1 = 2, so on so forth. To put it into perspective:

Simplifying & Fractions -> Decimals.

Fractions can be simplified, by being divided by a greatest common factor (GCF) . Let's imagine 4/8, where their greatest common factor is 4.

4/8 when simplified is 1/2. Putting this into diagram, we can find that this is true.

Can 3/8 be simplified? Of course not. But it would be a great example for how we can turn fractions into decimals. As mentioned earlier, fractions are division, instead of having "remainders" during division, you will end up with decimals.

To explain how to turn a decimal into a fraction, let's use a simple number, 0.25. You should know the places of decimals, the digit on the rightmost is on the hundredths place. Which means we will be multiplying our number by 100.

As you know, whole numbers can be made into 0.25/1, so we will be starting from there.

Operations with Fractions

Addition

When adding fractions, the numerators are the values you will be adding together, while the denominators stay the same. For example, 3/8 + 4/8.

What if their denominators are different, however? You can use multiple methods, however I am much more adept with using the LCM (Least common multiple) method.

In the LCM method, you have to find their least (smallest) common multiple. You divide the multiple by the denominator and multiply the quotient to the numerator. For example:

Subtraction

Subtraction works almost similar to addition, the only difference being that you subtract the numerators.

Multiplication

Multiplication is very simple, you multiply both the numerators and the denominators by one another.

Looking at the equation, you can still simplify the answer. Rather than coming up with two final answers, you can simplify the equation instead. But you may only do this with diagonal values. For example:

I am aware that you can simplify 6/4, which is an option as well. If the fraction can be simplified, then go ahead.

This applies with 2+ fractions.

Division

Division uses the operation of multiplication, however it has a few steps. There's a popular method to use for division of fractions, called the KCF (Keep-Change-Flip) method.

Keep the first fraction, change the sign from division to multiplication, and flip the 2nd (or more) fraction.

For 2+ fractions:

DOCTOR ITS MY BIRTHDAY!!!!

Happy birthday then to you.

I got 97 on math on my report card r u proud of me ‼️ (i didn't even review properly i just memorized the formulas)

I'm proud of you, dear student. Most of math is memorizing formulas in the first place, it's not ideal, but as long as you are able to understand how the formulas work, then keep going.

how do you feel about kiwis

Both the bird and the fruit have my acknowledgement. I harbor neutral feelings about them.

Hey, doc. I just wanted to send over my gratitude for your work, for everything you've contributed to the universe. I think it's better that Nous won't cast THEIR gaze on you. It's pretty scary when it happens. I wouldn't want a Dr. Ratio who's devoid of that core empathy that made him what he is today. So please, do stay the same, doc.

~Sincerely, a lowly mundenite from a far away world

//P.S: I sent you and the gambler matching rubber duckies 🐤 🐤

Thank you for this message. Being gazed by Nous THEMSELVES would not make me devoid of empathy. Treading a new path does not change a person, as that's why they get gazed upon in the first place.

Thank you for the duck.

What do you suggest for someone who has to study something they're not exactly passionate about but their interests aren't considered as profitable/stable

Keep up your interests while studying what you are not passionate about, and if you can, figure out a way to combine the two together so that you may be inspired to keep going.

[dr-vrat1o]

Dr. Ratio, what happens if I fail to get into my universities?

You try again. Not without taking a step back to understand how and why you failed, solving that problem, then attempting once more.

keep going autistic king

[dr-vrat1o]

Whenever I have trouble trying to study for my exams I always think about what the professor would say to encourage me and motivate me. Thank you for being a motivational reason to study <3

Of course. You must have a good motivation to do anything, otherwise you may fall into unhealthy habits. Keep going, dear student.

Hello! Just dropping off a random drawing I made of you! :D (Just please don't question why there's a black wiggly line covering whatever I wrote near the portrait of you. It's just some random text, nothing else really. )

I hope you like it! I worked so hard just to drew you so beautifully cause doctor, YOU'RE FREAKING MAJESTIC🥺😭

-From a girl who has an infrequent posting schedule in her blog💀

Thank you for this portrait. I'm glad you were able to capture my image well.

Blåhaj be upon ye 🦈

Thank you. I don't enjoy plush toys like this, but I know who would.

ok

[dr-vrat1o]

Dr Ratio will you give me a chance pleaseeee please pleeeasseee *gets down on both knees snivelling and sobbing pathetically* pleewasseee pleaaseee I'd be such a good partner pleewasseeeee let me hit just once plspslspslspls

No, pleading will get you nowhere.
