What is the simplest form for 15 over 45?

Answer 1

Okay what you have to do is divide the top and the bottom by 1 specific number and by specific i mean a number that can go into the numerator and denominator without any remainders!!

(example)OK so our question is: 15/45

so let's think of a number that go evenly into 15 and 45.

(note: if there is more than one number that goes into both the numerator and denominator than you have to pick the smallest one! this will make it easier*but not faster*)

so our number will be 5

so now divide 15divided by 5= 3 and 45 divided by 5= 9

so now our fraction is 3/9

now we have to pick another number that we can use to divide for this case we'll use 3

3/3= 1 and 9/3= 3

so our answer is 1/3 and we know this is the answer because we can't divide nay more!!

hope this helped?!?
