Question

If A:B = 5:18 and B:C = 6:4, form the ratio A:B:C​

Answer 1

Answer:

5 : 18 : 12

Step-by-step explanation:

Express the ratio B : C  in fractional form, that is

$\frac{B}{C}$ = $\frac{6}{4}$ ( cross- multiply )

6C = 4B ( divide both sides by 6 )

C = $\frac{4}{6}$ B = $\frac{2}{3}$ B , then

C = $\frac{2}{3}$ × 18 = 2 × 6 = 12

Hence

A : B : C = 5 : 18 : 12

Answer 2

Answer:

5:18:12

Step-by-step explanation:

5:18

_:6:4 --> since you multiply 6 by 3 to get 18, multiply 4 by three to get the A:B:C ratio.

5:18:12
