evablogger [386]

Answer:

The total yards of cloth needed for the flags = 28

Step-by-step explanation:

Given:

Jake and his dad are making (6,12,18) different types of flags.

Each flag takes (\frac{2}{3},\frac{3}{4},\frac{5}{6}) of a yard of cloth.

To find the total yards of cloth needed in all.

Solution:

Flag A :

Each flag requires = \frac{2}{3} of a yard of cloth

Total number of this flag = 6

Total cloth required for this flag = \frac{2}{3}\times 6 = 4\ yd

Flag B:

Each flag requires = \frac{3}{4} of a yard of cloth

Total number of this flag = 12

Total cloth required for this flag = \frac{3}{4}\times 12 = 9\ yd

Flag C:

Each flag requires = \frac{5}{6} of a yard of cloth

Total number of this flag = 18

Total cloth required for this flag = \frac{5}{6}\times 18 = 15\ yd

Thus, total yards of cloth needed for the flags = 4\ yd+9\ yd+15\ yd =28\ yd
