The area of the apartment is 55 m2, the area of the kitchen is 11 m2, what percentage of the area

The area of the apartment is 55 m2, the area of the kitchen is 11 m2, what percentage of the area of the apartment is the area of the kitchen?

The unknown number of percentages sought, which the kitchen area is relative to the area of the entire apartment, is denoted by the conditional variable “Y”.
Based on the conditions of this problem, we compose the following equation: Y = (11/55) x 100.
As a result of solving the resulting equation, we have the following Y = 0.2 x 100 = 20%.
Answer: the kitchen area is 20% of the area of the entire apartment.
