Question

A piece of wire is 290 cm long.

Dawid cuts three 25 cm lengths off the wire.
He then cuts the rest of the wire into as many 30 cm lengths as possible.
Work out how many 30 cm lengths of wire Dawid cuts.​

Answer 1

7

Explanation:

3 × 25 = 75cm

He cuts 75cm of 290cm so the remaining length is 290 - 75 = 215 cm

→ He then cuts the rest of the wire into as many 30 cm lengths as possible.

215 ÷ 30 = 7.17

Answer 2

8

Explanation:

(290-25)/30

265/30

8 and 5/6

so how many full 30 cm lengths?
