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»

Total length = 63 cm Ratio = 3 : 4

Sum of the ratio = 3 + 4 = 7

7 parts = 63 cm

1 part = 63/7 = 9 cm

3 parts = 3 × 9 cm = 27 cm

4 parts = 4 × 9 cm = 36 cm

∴ 63 cm can be divided into the parts as 27 cm and 36 cm.
