Answered by Ms. Sue
Since there are 100 cm in a meter, set up this fraction and solve.

48/100 = ?

If you try the second problem, we'll be glad to check your answer.
Answered by Mr. L.
Convert 48 cm into metres by dividing it by 48/100. You should come up with a decimal answer.

Convert all measurements into centimetres which leaves on 47 metres. To covert m into centimetres you have to multiply by 100.

From big measurement to small (m-cm) you need to multiply by multiples of ten(2 steps =100). From small measurements to large (cm-m) you need to divide by multiples of ten(2 steps =100)

Your first answer looks good, but make sure you have your units or measurement right for the second. Always check the units of measurement. My own students forget little pieces of info like that.
