Question

A line segment 63 cm long is to be divided into two parts in the ratio 3 : 4. Find the length of each part.

Answer 1

Total length $=63cm$ Ratio $=3:4$

Sum of the ratio $=3+4=7$

7 parts $=63cm$

1 part $=\frac{63}{7}=9cm$

3 parts $=3\times 9cm=27cm$

4 parts $=4\times 9cm=36cm$

$\therefore 63cm$ can be divided into the parts as $27cm$ and $36cm$.
