What are ratios and proportions?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

It is given that

$\dfrac{a}{b}=\dfrac{1}{5}$

$b=5a$..............1

Also the second relation

$\dfrac{a}{c}=\dfrac{2}{1}$

$a=2c$..................2

Put the value of an in equation 1

$b=5\times 2c=10c$

Hence the value of b will be 10 times bigger than the value of c. for the given ratio a:b=1:5 and a:c=2:1
