I need help! I forgot how to do this!! Please help!
Dovator [93]

First change the mixed fraction into an improper fraction

7 1/2 = 15/2

Next, change multiply 2 to both numerator and denominator

15 x 2 = 30

2 x 2 = 4

30/4

Each piece needs 3/4 of an inch. Divide 30 with 3

30/3 = 10

c) 10 pieces is your answer

hope this helps
