a crew is made up of 14 men; the rest are women. 66 2/3% of the crew are men. how many people are in the crew?

Westkost [7]

There are 21 people in the crew.

Step-by-step explanation:

Given,

Number of men in the crew = 14

Percent of men = $66\frac{2}{3}=\frac{200}{3}$ %

Let,

x be the number of people in crew.

According to given statement;

$\frac{200}{3}\% \ of\ x=14\\\\\frac{200}{3*100}x=14\\\\\frac{200}{300}x=14$

Multiplying both sides by $\frac{300}{200}$

$\frac{300}{200}*\frac{200}{300}x=14*\frac{300}{200}\\x=7*\frac{300}{100}\\x=7*3\\x=21$

There are 21 people in the crew.
