To understand how to do this problem, we have to look at examples to figure it out. One example would be, if I had a whole cake and cut into 2 pieces I would have two halves, and if I cut it into 4 pieces, I'll have 4 quarters of cake, so 2/2 (two halves) = 4/4 (4 quarters). If I ate 1/2 I would have
(Keep in mind that Equivalent fractions are fractions that are equal to each other)
So to solve these we have to figure out the equal fractions. To do this, we start by multiplying by 2.
(the * symbol is multiplication)
So 3/4 would be 3*2=6 and 4*2=8 so it would be 6/8
Now we can try multiplying it by 3
3*3=9 and 4*3=12 so the 2nd would be 9/12
And we multiply it by 4 now,
3*4=12 and 4*4=16 so the 3th would be 12/16
So, therefore, the answers for 3/4 are 6/8, 9/12, & 12/16.
I'm also going to give you a simplified number that you can use to solve the other problems easier.
3/7 is 3/7. (cannot be simplified)
18/27 is 2/3.
20/80 is 1/4.
You can use these three numbers to start and multiply by 2 and 3 for the other two numbers.
I just gave you a very easy was to solve them and a simple calculator or doing the simple math will be able to help you figure out the rest.
Good luck!
