1costume

`\\ \rm\hookrightarrow (27)/(4)/ 3`

`\\ \rm\hookrightarrow (27)/(4)* (1)/(3)`

`\\ \rm\hookrightarrow (27)/(7)yards`

7costumes

`\\ \rm\hookrightarrow (27)/(7)* 7`

`\\ \rm\hookrightarrow 27yards`

Answer 2

Finds how much is needed for 1 costume by dividing 6 3/4 by 3

6 3/4 /3 = 2 1/4 yards per costume.

Multiply yards per costume by 7:

2 1/4 x 7 = 15 3/4 yards total needed.
