Question

A wall with an area of 4 m2 was painted yellow and brown. The area of the wall painted
yellow was 3 times as large as the area painted brown.

What was the ratio of the area painted yellow to the area painted
brown?



What fraction of the total area of the wall was painted brown?
Find the area of the wall painted yellow.

Answer 1

Answer:

• Ratio of the area painted yellow to the area painted brown = 3:1

• Fraction of the total area of the wall was painted brown = 1m²/4m²

• Area of the wall painted yellow = 3m²

Step-by-step explanation:

Given

Area of the wall = 4m²

Area painted brown = x

Area painted yellow = 3x

-------------------------------------------------------

Therefore,

Ratio of the area painted yellow to the area painted brown = 3:1

-------------------------------------------------------

Total Ratio = 3:1 = 3+1 = 4

Area painted brown = 1m²

Area painted yellow = 3m²

-------------------------------------------------------

Fraction of area painted brown

= 1x m²/4m²

= 1m²/4m²

Fraction of area painted yellow

= 3m²/4m²

-------------------------------------------------------
