Question

Dave has 25 3/4 feet of piping and needs to cut it in 1 1/2 foot measurements for a project. How many pieces of piping will he end up with?

Answer 1

Answer: 17 1/6 or 17-18

(u guess which is right if its an integer ^^)

Explanation:

25 3/4 ÷ 1 1/2

First change the mixed fractions to improper fractions.

25 3/4 = 103/4

1 1/2 = 3/2

Now divide: 103/4 ÷ 3/2

103/4 * 2/3 (multiply by flipping the second fraction)

= 206/12

Now divide: 206 ÷ 12

= 17 2/12 (simplified: 17 1/6)

The answer will be 17 1/6 (OR 17-18)
