Question

The amount of sugar and flavouring used for an ice cream is as follows:


The ratio of the amount of sugar to the amount of flavouring is

• A. 2:1
• B. 1:1
• C. 1:2
• D. 3:5

Answer 1

The correct option is A 2:1

$\text{Amount of sugar used}=\frac{3}{5}\text{kg}=\frac{3\times 2}{5\times 2}\text{kg}=\frac{6}{10}\text{kg}$

$\text{Amount of flavouring used}=\frac{3}{10}\text{kg}$

$\text{Hence, the fraction of amount of sugar}\text{to amount of flavouring is:}$

$\frac{\text{Amount of sugar}}{\text{Amount of flavouring}}=\frac{\left[\frac{6}{10}\right]}{\left[\frac{3}{10}\right]}=\frac{6}{3}$

Now we can represent the fraction as:
$\frac{6}{3}=\frac{6÷3}{3÷3}=\frac{2}{1}$

$\text{Representing the fraction as a ratio,}\text{we get:}\frac{2}{1}⟹2:1$

∴ The ratio of amount of sugar to amount of flavouring is 2:1
