Answer:

790cm

Step-by-step explanation:

Briana buys a reel of thread for sewing. There are 10 m of thread on the real. Her brother in grade 4 used 210 cm. How much is left on the reel in centimeters?

1m = 100cm

10m = x

x = 10 × 100cm

x = 1000cm

The total number of thread on the reel = 1000cm

The amount of thread left on the reel is calculated as:

The total number of thread on the reel - The amount of thread on the reel that was used.

= 1000cm - 210cm

= 790cm
