Here are some examples of decimal word problems. We will illustrate how block diagrams can be used to help you to visualize the decimal word problems in terms of the information given and the data that needs to be found. Block diagrams are used in Singapore Math.

Example:

Lily used some cloth to make 4 banners and a tablecloth. She used 1.95 m of cloth for each banner and 1.24 m of cloth for the tablecloth. How many meters of cloth did she use altogether?

Solution:

Step 1: Find the total length of cloth used to make the 4 banners.

1.95 × 4 = 7.8

The total length of cloth used to make the 4 banners was 7.8 m.

Step 2: Find the total length of cloth Lily used altogether.

7.8 + 1.24 = 9.04

Lily used 9.04 m of cloth altogether.




Example:

Joe bought 7 liters of orange juice. He poured the orange juice equally into 5 bottles. There was 0.25 liters of orange juice left. What was the volume of juice in 1 bottle?

Solution:

Step 1: Find the total volume of orange juice in the 5 bottles.


7 – 0.25 = 6.75

The total volume of orange juice in the 5 bottles was 6.75 liters.

Step 2: Find the volume of orange juice in 1 bottle.


6.75 ÷ 5 = 1.35

The volume of orange juice in 1 bottle was 1.35 liters.
