Question

Brent bought a reel of thread that is 15.25 metres long. Brent uses 575 centimetres for a project. How much thread in centimetres is left on the reel?

Answer 1

There would be 950 cm of thread left on the reel

Explanation:

Here in this question, we are interested in knowing the amount of thread left on the reel.

To answer this question properly, we shall need to be consistent in using our units.

Thus, we need to convert the length of thread on the reel to cm.

Mathematically;

100cm = 1 m

let x cm = 15.25 m

x = 15.25 * 100 = 1525 m

Since 575 cm has been used for a project, the amount of thread in cm left on the reel will be;

1525 cm - 575 cm = 950 cm
