Question:

Kim's hair was 42.5 cm long. She had 43 mm cut off. How long is her hair now?

Answer:

Now, the length of Km's hair is 38.2 cm.

Given:

Kim's hair was 42.5 cm long.

She had 43 mm cut off.

To find:

How long is her hair now?

Explanation:

1 cm = 10 mm.

∴ 42.5 cm = (42.5×10)

                 = 425 mm.

∴ The length of Kim's hair was 425 mm.

She had 43 mm cut off.

∴ The present length of her hair is_

(425-43) mm

= 382 mm

= (382÷10) cm [∵ 1 cm = 10 mm or, 1 mm = 0.1 cm.]

= 38.2 cm.

∴ The present length of Kim's hair is 38.2 cm.
