5th Grade Word Problems

The following are some examples of 5th Grade Math Word Problems that deals with ratio and proportions.

 

 

Example:

A zoo has 96 chickens and ducks altogether. The ratio of the number of chickens to the number of ducks is 5:3. How many chickens does the zoo have?

Solution:


Total number of units = 5 + 3 = 8

8 units → 96

1 unit → 96 ÷ 8 = 12

5 units → 5 × 12 = 60

The zoo has 60 chickens.

 

 

Example:

Charlie divides a basket of cherries into two portions. The ratio of the mass of the bigger portion to the mass of the smaller portion is 5: 2. If the mass of the bigger portion is 15 kg, find the mass of the smaller portion.

Solution:


 

5 units → 15 kg

1 unit → 15 ÷ 5 = 3 kg

2 units → 2 × 3 = 6 kg

The mass of the smaller portion of cherries is 6 kg.
