A: b = 1:6
a:c = 3:1
How many times bigger is b than c?

B is 18 times bigger than C.

Given that,

Based on the above information, the calculation is as follows:

And,

Now we have to cross multiplied

So it comes 18

Therefore we can conclude that B is 18 times bigger than C.

Step-by-step explanation:

Expressing the ratios in fractional form

= ( cross- multiply )

b = 6a → (1)

= ( cross- multiply )

a = 3c ← substitute into (1) , thus

b = 6 × 3c = 18c

Then b is 18 times bigger than c
