Answer 1

i hope this help you

Answer 2

A : B : C= 15 : 12 : 10

Step-by-step explanation:

Let 4A = 5B = 6C = k

Where, k is constant

To find, the value of A : B : C =

∴ 4A = k

⇒ A $=\dfrac{k}{4}$

5B = k

⇒ B = $\dfrac{k}{5}$

And

6C = k

⇒ C = $\dfrac{k}{6}$

∴ $A:B:C=\dfrac{k}{4}:\dfrac{k}{5}:\dfrac{k}{6}$   ....(1)

The LCM of 4, 5 and 6 = 60

Multiplying (1) by 60, we get

$A:B:C=\dfrac{60}{4}:\dfrac{60}{5}:\dfrac{60}{6}$

⇒ A : B : C = 15 : 12 : 10

Hence, A : B : C= 15 : 12 : 10
