Question

If A:B=5:6and B:c=4:7, find A: B:C​

Answer 1

Answer:

we can see that —————→ a/b=4/7

❥ b=7a/4

Now notice that b/c=5/6 , then ———-> b=5c/6

Now substitute to get,

7a/4=5c/6

❥ c=21a/10

So we want ————-> a:b:c

express b and c in terms of a

❥ a:7a/4:21a/10

Multiply all sides by 20 to get,

✧*。20:35:42✧*。
