Question

A roll of ribbon was 12 meters long. Diego cut 9 pieces of ribbon that were 0.4 meter each to tie some presents. He then used the remaining ribbon to make some wreaths. Each wreath required 0.6 meter. a. How many meters of ribbon were available for making wreaths?

Answer 1

8.4 meters

Explanation:

According to the problem, computation of the given data are as follows:

Ribbon roll = 12 meter

Number of pieces cut = 9

Length of each piece = 0.4 meter

So, total length cut = 0.4 × 9 = 3.6 meters

So, we can calculate the ribbon available for making wreaths by using following formula:

Ribbon available after cut = Ribbon total length - Total length cut

By putting the value,

Ribbon available for wreaths = 12 meters - 3.6 meters

= 8.4 meters
