An art and craft project require 42 pieces of wire. each length 1 4/7 feet. Assuring there is no waste in cutting, calculate the length of wire that should be purchased

66 feet.

42 * (11/7) = 462/7 = 66 ft

To calculate the total length of wire that should be purchased for the art and craft project, we need to multiply the number of pieces of wire required by the length of each piece.

Given that the project requires 42 pieces of wire and each piece is 1 4/7 feet long, we can break down the calculation as follows:

1. Convert the mixed fraction into an improper fraction:

1 4/7 can be written as (7 * 1 + 4) / 7 = 11 / 7

2. Multiply the number of pieces of wire by the length of each piece:

42 * 11 / 7 = 462 / 7

3. Simplify the fraction:

462 / 7 = 66

So, the length of wire that should be purchased for the art and craft project is 66 feet.
