Question

Mark has 23 feet of string. He will cut the string into equal lengths of 9 inches each. How much string will be left after he cuts as many pieces of these lengths as possible?

Answer 1

Convert foot to inches:

1 foot = 12 inches

23 feet ⇒  23 feet × 12 inches/ft = 276 inches

Divide:

276 ÷ 9 = 30 pieces with remainder

Remainder = 276 - (9×30)  ⇒  276 - 270 = 6

ANSWER: There will be 6 inches long remaining in length after cutting the string into 30 pieces equal lenght of 9 inches each.
