What is 5/7+3/4?

Question

and how do you get there?

Answer 1

Hi Dena Lisa. To add these fractions you need to generate a common denominator - you can only add fractions with a common denominator. 28 is the lowest common denominator so:

1) multiply 5/7 by 4/4: this gives:
20/28

2) multiply 3/4 by 7/7: this gives:
21/28

3) add 20/28 to 21/28: this gives:
41/28

4) 41/28 cannot be reduced, so the final answer is 41/28 (which is the same as 1 13/28).

Hope this helps you. Best wishes and good luck.

Answer 2

5/7 + 3/4 = 20/28 + 21/28 = 41/28 = 1 13/28

Answer 3

first you have to find a common denominator
the lowest number that is divisible by both 7 and 4 is 28
multiply both fractions to be /28 - 5 x 4/7 x 4 = 20/28 and 3 x 7/4 x 7 = 21/28
then you can just add the numerators - 20 + 21 = 41
that gives you 41/28
41 is prime so it can't be simplified so your final answer is 41/28

Answer 4

5/7+3/4

first find a common denominator, wich is 28, so you mulitply 5/7 but 4/4 and 3/4 by 7/7 and after that, you get 20/28 and 21/28.

20/28+21/28=41/28

if you have to get rid of the improper fraction, then just divide 41 by 28 and then you'd get 1 13/28.

hope this helps. =]
