Question

if a ratio b is equals to 2 ratio 3 and B ratio c is equal to 4 ratio 5 find C ratio a​

Answer 1

Answer:

Step-by-step explanation:

A:b = 2:3

A= 2k , b = 3k

B:c = 4:5

B = 4k , c = 5k

C:a = 5k / 2k = 5:2

Answer 2

Answer:

15 : 8

Step-by-step explanation:

Given,

A : B = 2 : 3

Let A = 2x and B = 3x,

Where, x is any real number.

B : C = 4 : 5

Let B = 4y and C = 5y,

Where y is any real number,

⇒ 3x = 4y

⇒ x = $\frac{4y}{3}$

⇒ A = 2x = $2\times \frac{4y}{3}$ = $\frac{8y}{3}$

Thus, C : A = 5y : $\frac{8y}{3}$

= 15 : 8
