Question

a piece of wire is 240cm long.

peter cuts two 45cm lengths off the wire.
He then cuts the rest of the wire into as many 40cm lengths as possible.

work out how many 40cm lengths of wire peter cuts

Answer 1

The answer is 3.

First peter cuts off two 45 cm lengths.
Then that leaves (240-45-45) cm length left... ie 150 cm.
Then he cuts of as many 40cm lengths as possible.
So, we divide the remaining length by 40.


Therefore,
150/40= 3

But 30 cm is leftover.... which is less than 40.. so it is not considered.



Hope the answer helps you..
