Question

A recipe requires $\frac{2}{3}$ tablespoon of salt. How much salt is need to prepare $\frac{1}{3}$ of the similar recipe?

• A. $\frac{2}{9}$
• B. $\frac{9}{2}$
• C. $18$

Answer 1

The correct option is A $\frac{2}{9}$

Part of teaspoon required to make 1 recipe $=\frac{2}{3}$
Part of teaspoon required to make $\frac{1}{3}$ of the recipe $=$ Part of teaspoon required to make 1 recipe $\times \frac{1}{3}$
$=\frac{2}{3}\times \frac{1}{3}$

To multiply the fractions multiply the top numbers and multiply the bottom numbers

$=\frac{2\times 1}{3\times 3}$

$=\frac{2}{9}$
Hence, $\frac{2}{9}$ teaspoon of salt are required to make $\frac{1}{3}$ recipe.
