Question 7(d)

Find the ratio of the following:

500 ml to 2 litres

Answer 1

Ratios are used to compare quantities which have same units

To find the ratio of the given numbers we have to convert them into same units.(Since the units of two numbers are different ,i.e.one is in ml and other in litres).

2 litres = 2 $\times$ 1000 ml = 2000 ml [$\because$ 1 litre = 1000 ml]

Now, ratio of 500 ml to 2 litres = 500 ml : 2 litres

= 500 ml : 2000 ml = $\frac{500}{2000}$

= $\frac{1}{4}=1:4$ [Dividing numerator and denominator by HCF of 500 and 2000 i.e. 500]
