Question

if 4a = 5b and 3a = 2c then the ratio of b : c =​

Answer 1

Answer:

8:15

Step-by-step explanation:

the below values satisfy in equation

a= 10

b= 8

c= 15

you can deduce value of one variable and put the value in other one

Answer 2

The ratio of b:c is 8:15.

Given:

4a = 5b

3a = 2c

To Find:

The ratio of b and c.

Solution:

We are required to find the value of the ratio of b and c.

We are given 4a = 5b and 3a = 2c which can be written as

4a = 5b

b = (4/5)a  -------(1)

3a = 2c

c = (3/2)a  --------(2)

For the ratio of b and c, Divide equation(1) by equation(2) we get

b/c = (4/5)a / (3/2)a

b/c = 4×2/5×3

b/c = 8/15

b:c = 8:15

Therefore, The ratio of b:c is 8:15.
