Question

divide a line segment 45 cm into three parts whose ratio is 5:7:3​

Answer 1

15 cm, 21 cm and 9 cm

Step-by-step explanation:

Let us consider, the segment after dividing be,

5x : 7x : 3x

5x + 7x + 3x = 45 cm (Given)

15x = 45

x = 3

5x = 5×3 = 15

7x = 7×3 = 21

3x = 3×3 = 9

Therefore, the segment should be cut in three parts as 15 cm, 21 cm and 9 cm.
