Answer:
13 costumes
Step-by-step explanation:
The amount of fabric used is the product of the amount per costume and the number of costumes.
A = na . . . . . A = total area; n = number of costumes; 'a' = area per costume
46 2/3 = n(3 1/2)
n = (46 2/3)/(3 1/2) = (140/3)/(7/2) = (140/3)(2/7) = 40/3 = 13 1/3
Apparently there is some waste, as Emerson used more fabric than necessary to make 13 costumes.

Step-by-step explanation:
Equal groups are illustrations of using the same variable.
A word problem that uses equal group is:
Christopher traveled a distance of 5 miles yesterday; he traveled a distance of 4 miles earlier today. Calculate the total distance traveled
The only condition for equal groups is that:
The units or variable must be the same
For instance:
Add 5 miles and 4 miles ----- This represents distance
Remove 2 liters from 7 liters --- This represents volume
Add 5 hours and quarter of an hour -- This represents time
And so on.
