Question

A $21meters$ long pipe is to be cut into two pieces, with the lengths of the pieces being in a ratio $2:5$.

What are the lengths of the pieces?

Answer 1

Find the lengths:

The ratio of the lengths = $2:5$

Length of the pipe = $21meters$

Sum of the terms of the ratio = $2+5=7$

Length of the first piece = $\frac{2}{7}\times 21=2\times 3=6meters$

Length of the second piece = $\frac{5}{7}\times 21=5\times 3=15meters$

Hence, the lengths of the pieces are $6metersand15meters$.
