Answer:
Option A) 1 : 3
Step-by-step explanation:
A bag contains 16 red, 4 yellow, 20 blue and 8 white balloons.
Total balloons in a bag = 16 + 4 + 20 + 8
= 48 balloons
The part to whole ratio of red balloons
= 16 : 48 [simplify it]
= 8 : 24
= 1 : 3
The ratio is 1 : 3
Option A) is the correct answer.
