Answer 7

u have to make the fractions have the same denominator. so we find the lcm which is 20 in this case. multiply the top and bottom by a number that makes the denominator 20
(4/5)(4/4)=16/20
(1/4)(5/5)=5/20
16/20 is the same as 4/5
and
5/20 is the same as 1/4 so we can substitute the values
4/5+1/4=16/20+5/20
now that the denominator is the same we can add the numerator
(16+5)/20
21/20
