Question

A company has 110 employees, of which 70% are temporary. How many temporary employees are there?

• A. $50$
• B. $7$
• C. $70$
• D. $77$

Answer 1

The correct option is D $77$

$\text{Total number of employees}=110$

Number of temporary employees

$=70\%\text{of}110$

$=\frac{70}{100}\times 110$

Let's simplify $\frac{70}{100}$

$=\frac{7\times 10}{10\times 10}\times \frac{110}{1}$

Cancel out the common factors
$=\frac{7}{10}\times \frac{110}{1}$

Multiply the numerators (7 and 110) & denominators (10 and 1)
$=\frac{7\times 110}{10\times 1}$

$=\frac{770}{10}$

Simplify the fraction
$=\frac{77\times 10}{10}$

Cancel out the commom factors
$=77$
