Randy just added up the numbers on the numerator and denominator.

This is incorrect.

Correct way of adding the fractions given below:

7/8 + 9/15 =                      ⇒ Simplify the second equation, divide by 3)7/8 + 3/5 = 5*7/5*8 + 8*3/8*5 =         ⇒ Bring both fractions to common denominator of 4035/40 + 24/40 =              ⇒ Add up the numbers in the nominator54/40 =                            ⇒ Simplify by dividing by 227/20 = 1 7/20                               ⇒ Convert to mixed fraction

The reporter forgot to multiply the decimal by 100, making it 25%
