Question

Lucy colored $\frac{3}{10}$ parts of a floor. If the floor is divided into $100$ equal parts, how many parts did she color?

• A. $\frac{30}{100}$ parts
• B. $\frac{100}{100}$ parts
• C. $30$ parts
• D. $10$ parts

Answer 1

The correct option is C $30$ parts

To calculate the parts out of $100$ for $\frac{3}{10}$, we need to convert the fraction into an equivalent fraction with $100$ as the denominator.
Multiplying the numerator and denominator by $10,$
$\frac{3\times 10}{10\times 10}=\frac{30}{100}$

Hence, Lucy colored $30$ parts out of $100$.
