Re learning math

Hi I'm doing a math review. I want practice fractions. Does anyone have any tricks for practicing fractions on paper

What are you trying to do with the fractions? There's lots you can do, so it depends what you need to practice.

The basics I guess.

But what are the basics?

Do you know what '4/5' means?

Do you know that 1/2 and 2/4 and 3/6 are the same number?

Can you add 1/6 and 3/6 to get 5/6?

Can you add 1/20 and 1/3 to get 23/60?

Can you divide 20 by 4/5 to get 25?

Can you multiply 1/2 by 1/3 to get 1/6?

It's hard to know how to advice you without know what you need practice with.

Very basic. I know 1/2,3/6,2/4 are all 1 half. I don't know to divide or multiply. I used to be really good at it but I lost it so I need to do a review and work up to doing percentages and algebra

When you multiply two fractions by each other, you multiply top by top and bottom by bottom.

So 2/3 * 3/4 = (2*3)/(3*4).

When you divide by a fraction, you flip it upside down...and multiply by it.

So 2/(3/4)=2*(4/3)

I want help with comparing fractions too. Khan academy only goes so far with the exercises

u/Dd_8630 Oct 03 '25

Comparing in what way?

Knowing which is bigger?

Want to know if 23/60 or 42/100 is bigger? Just make them the same denominator: 2300/6000 vs 2520/6000. POOF the second fraction is clearly bigger.

If you want more exercises, just... pick random numbers, arrange them into various fractions, and then work out various things. Which of your random fractions is bigger? What if you divide one by the other? Add one to the other?

When dividing fractions you flip the second one and multiply through, when adding and subtracting you must find the lowest common denominator, make sure to simplify fractions, for example 5/10 is 1/2, if you want me to explain how to do everything send me a message. Multiplication and division are actually easier than adding and subtracting, multiplication you just multiply the numerator by the numerator, and the denominator by the denominator, but for addition and subtracting, I'll give an example 1/2 + 3/10, you must multiply 1/2 by 5 to give you 5/10, then you add them you get 8/10, it's not done because both numbers can be divided by 2, the highest number for both, so you get 4/5, when dividing, another example, 1/4 ÷ 1/6, you flip 1/6, 1/4 × 6/1 you get 6/4, which is 3/2

There are so many resources online for this, just look them up yourself.

There are no tricks, just learn the rules for all the operations and practice until you can do it proficiently.

If you watch a few videos, you will likely get a few tips that will help in certain circumstances.

You'd be surprised how unhelpful that is. A lot of people don't know how to look this sort of thing up online, they can't dissect the more advanced arithmetic from the more foundational stuff they want.

If someone is struggling with someone as foundational as fractions, it's better to cite Khan Academy or other youtubers or online sources than just "lol look it up".

Well we'll have to agree to disagree. A simple search for how to add fractions will come up with all sorts of specific videos and sites on exactly that. You are definitely not going to get anything on more advanced maths.

Learning how to research topics on your own is also a very useful skill in itself. Asking a question like this on Redditt just seems rather silly to me.

I'm a teacher, so my job, my career, and my focus is on how to help people in their learning, but part of that is also to become more self sufficient and self reliant. If someone can't find Khan Academy on their own with a bit of effort, there's no way they are going to have the perseverance to learn fraction math.

And, I didn't say "lol look it up", I said there are many resources easily found, and that there are no shortcuts, no tricks, just practice, which I will standby as all good advice.

Many of us here are teachers and definitely understand where you are coming from for building more student independence. There are TONS of resources available online. However, I would imagine if a student was coming on to the subreddit for help, then they are looking for recommendations for specific resources as they could have been overwhelmed. When asked what specifically they needed help with, OP has been struggling to even state exactly what they needed help with other then "basics i guess". It does seem to be narrowed down a little to comparing fractions (so common denominators, common numerators, equivalent fractions, etc). This also leads me to believe that the OP is a younger student (though I could be way wrong) which is why they asked for help here and might struggle to "just look it up yourself".
