Question

How do you simplify the fractions 4/5 + 3/4 in lowest terms

Answer 1

31/20

Explanation:

First we find the greatest common denominator, for 5 and 4, that is 20.

`(4)/(5) *(4)/(4) +(3)/(4)*(5)/(5) = (16)/(20) +(15)/(20) = (31)/(20)`

Since 31/20 isn't able to be simplified because 31 is a prime number, this is your final answer.

Answer 2

first find common denominator by multiplying.

5•4=20

16/20+15/20=31/20=1 11/20
