hey i am in 7th grade....and i never understood the simple steps!!
Wow...do you mean adding or subtracting or multiplying or dividing them?
To add, you need to make common denominators (the bottom part) for both fractions
no .i am not stupid though.. can you show me a problem?
So, for 1/2 + 3/4, you need to get both to have a bottom of 4. That's a number that both 2 and 4 go into.
So you'd multiply 1/2 by 2/2, because to multiply fractions you just multiply the tops and bottoms, getting 2/4
And if you know simplifying fractions you know that 1/2 is the same as 2/4, so this always works
But you always need to multiply by 2/2 or 5/5 or whatever, because otherwise you're not multiplying by 1 (2/2 or 5/5 are both just 1)
Good so far?
So then, to add them you can just add the tops...BUT KEEP THE BOTTOM THE SAME.
So 1+2=3, so your answer is 3/4
wow i am very stupid... well thanks
Then, for subtraction, it's the same thing, except you subtract the top numbers instead of adding them (duh!)
And then I showed you multiplication already (when you get common denominators)
So that leaves division.
You just reverse the second fraction and multiply them, so 1/2 divided by 3/4 would really just be 1/2 x 4/3
Which gives you 4/6, which you simplify into 2/3
You do know simplification of fractions, right?
Well, anyway, you just divide both the top and the bottom normally by a number they both go into.
Got all of that?
