Answer:
a / b = 1/7
b = a x 7
a / c = 4 /1
a = c x 4
b = a x 7
= c x 4 x 7
= c x 28
b is 28 times bigger than c
b is 28 times bigger than c. The conclusion is obtained by rearranging the equations.
What exactly are ratio and proportion?
A ratio is an ordered pair of integers a and b, expressed as a/b, where b cannot be zero. A proportion is an equation that sets two ratios equal to each other.
The given ratio;
a: b = 1:7
a:c= 4:1
Rearrange the given ratio we obtained;
b = a × 7
a = c × 4
Put the value of a in b get;
b= c × 4 × 7
Hence, b is 28 times bigger than c.
