Answer:
Given:
Area of wall = 84 m²
Area of wall painted = 21 m²
Asked: Percentage of wall left unpainted
Operation: Subtraction, then division
Number Sentence:
Area of unpainted wall = Total Area of wall - Painted wall
% = Area of unpainted wall/ Total area of wall
Solution:
Area of unpainted wall = 84 m² - 21 m²
= 63 m²
% = 63 m²/ 84 m²
= .75 = 75%
