Question

25 ml is ______ percent of 5 litres.

Fill in the Blanks

Solution

25 ml is 0.5 percent of 5 litres.

Explanation:

Let 25 ml be x% of 5 litres

Then, 25 ml = x% of 5 litres

⇒ 25 = `x/100 xx 5 xx 1000`  ......[∵ 1 l = 1000 ml]

⇒ `(25 xx 100)/(5 xx 1000)` = x

⇒ x = 0.5

Hence, 25 ml is 0.5% of 5 litres.
