Question

Solve the proportion b+4/5=7/4

Answer 1

Explanation:

When adding or subtracting fractions, they must have a common denominator....20 is the easiest for these...this then becomes

b + 16/20 = 35/20 now subtract 16/20 from both sides of the equation

b = 35/20 - 16/20

b = (35-16)/20 = 19/20
