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.
