Answer 1

`15:24:40`

Explanation:

`~~~150:240:400\\\\=(15 * 10):(24 * 10):(40 * 10)\\\\=15:24:40`

Answer 2

15 : 24 : 40

Explanation:

Prime factorizing each term :

⇒ 150 = 5² × 3 × 2

⇒ 240 = 2⁴ × 5 × 3

⇒ 400 = 5² × 2⁴

⇒ The HCF is 5 × 2 = 10

⇒ Remove this factor when taking the ratio

==========================================================

Taking the ratio :

⇒ 150 : 240 : 400

⇒ 5 × 3 × 2 : 2³ × 3 : 2³ × 5

⇒ 15 : 24 : 40
