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

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