Question

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

Answer 1

Answer:

b) 41¼

Step-by-step explanation:

16½ = 33/2

2½ = 5/2

(33/2) × (5/2)

165/4

41 ¼

Answer 2

Answer:

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
