Monicals 39/500 inches thick. 15 nickels are stacked vertically. How many inches tall is the Stack? Give your answer as a decimal

Answer 1

1.17 inches

Explanation:

If one nickel is 39/500 inches thick, then fifteen nickels would be fifteen times that.

So the answer will be 15 × 39/500 which equals 117/100 which equals 1.17 when converted to decimal.
