A plumber has a 2.5 metre long copper pipe
Anastaziya [24]

We have an object measured in <u>Meters</u>, and we want to cut sections of it off in <u>Centimeters</u>, a different unit of measurement.

Because we're subtracting sections of the pipe, we want to make the units the same, this will make our calculations easier.

1 Meter = 100 Centimeters, so, <u>2.5 Meters = 250 Centimeters</u>

We're cutting ( 60 Cm + 35 Cm + 90 Cm ) off, which totals <u>185 Cm</u>.

250 Cm Pipe - 185 Cm Cuts = 65 Cm Pipe Left
