A bolt has 16-1/2 turns per inch. How many bolts would be in 2-1/2 inches?

a

32-1/2

b

41-1/4

c

18-1/4

d

32

41 1/4

Step-by-step explanation:

Change 16 1/2 to a mixed number

16 1/2 = (2*16+1) / 2 = 33/2

Change 2 1/2 to a mixed number = (2*2+1) / 2 = 5/2

Multiply the turns per inch by the inches

33/2 * 5/2 = 165/4

Change this back to a mixed number

4 goes into 165 41 times

41*4 = 164 there is 1 left over

41 1/4
