Question

if a : b = 7:5 and b:c is equal 9-14 find a ratio c​

Answer 1

Answer:

A:B=7:5 AND B:C=9:14

So take out the LCM of the B=45

So make B into 45=》

A:B=(7×9):(5×9) AND B:C=(9×5):(14×5)

A:B=63:45 and B:C=45:70

So;A:C=63:70

Making it in simplest form the answer would be

A:C=9:10

Hope it helps:)
