Question

If a:b=4:5 and b:c=6:7 find a:b:c.​

Answer 1

Answer:

a:b = 4:5

b:c = 6:7

LCM of b that is 5 and 6 = 30

4x6=24=a

7x5= 35=c

Therefore , a:b:c = 24:30:35

Answer 2

Answer:

A:B:C = 24:30:35.

Hope ! it helps you.

Step-by-step explanation:

A:B = 4:5 (A/B = 4/5)

B:C = 6:7 (B/C = 6/7)

Now, for making the B value same we have to take the L.C.M of 5 and 6.

The L.C.M of 5 and 6 is 30.

A/B=4/5×6/6=24/30.

B/C = 6/7 × 5/5 = 30/35.

So, A:B:C = 24:30:35.
