`3/4+3/20 `
To add 2 fractions, you'll have to have the same denominator.
The least common denominator is 20 = 4*5.
We'll multiply by 5 the 1st fraction:
(3*5 + 3)/20
We'll factorize by 3:
(3*5 + 3)/20 = 3(5 + 1)/20
We'll add what is inside brackets:
3(5 + 1)/20 = 3*6/20
3(5 + 1)/20 = 18/20
3(5 + 1)/20 = 2*9/2*10
3(5 + 1)/20 = 9/10
The result of adding the given fractions is: 3/4+3/20 = 9/10.
