Question

4. IfA:B= 3:5 and B:C=7:11. find:
a) A:C
b) A:B:C​

Answer 1

Answer:

a. A:C=3:11

b. A:B:C=3:5:11

Answer 2

Step-by-step explanation:

(a)A:B = 3:5

B:C = 7:11

A:B * B:C = A:C

3:5 * 7:11 = 21:55

so , A:C = 21:55

(b) As you can see that the alphabet B is present in both ratio so try to make the alphabet B same in both ratio.

We can do this by multiplying the first ratio by 7 and second ratio by 5 we get,

A:B = 21:35

B:C = 35:55

A:B:C = 21:35:55

Hope it helps.
