Question

3. A bolt has 16 ½ turns per inch. How many turns would be in 2 ½ inches of bolt?

Answer 1

I believe it would be 41.25, just multiply the two numbers. Hope this helps

Answer 2

so, per inch bolt turns = 16 1/2 = when it is a mixed number it is 33/2 

so, if 2 1/2 = 5/2 inches bolt turns = 33/2 x 5/2 
=16 5/4 
hence 41 1/4 turns
