Example Question #61 : Grade 6

Red is a very popular car color. A production company manufactures cars and parks them in a lot behind the plant. There are 100 cars in the parking lot and $60 \%$ of them are red. How many red cars are in the parking lot?

Possible Answers:

Correct answer:

Explanation:

We can use ratios and proportions to solve this problem. Percentages can be written as ratios. The word “percent” means for every hundred. In the problem, we are told that $60\%$ of the cars are red. In other words, for every hundred cars of them are red. We can write the following ratio:

$60:100\rightarrow\frac{60}{100}$

Reduce.

$\frac{60}{100}\rightarrow \frac{6}{10}\rightarrow \frac{3}{5}$

We know that there are 100 cars in the parking lot. We can write the following ratio by substituting the variable Red for the number of red cars:

$Red:100\rightarrow \frac{Red}{100}$

Now, we can create a proportion using our two ratios.

$\frac{3}{5}=\frac{Red}{100}$

Cross multiply and solve for Red .

$5 \times Red=3\times100$

Simplify.

5 Red=300

Divide both sides of the equation by .

$\frac{5Red}{5}=\frac{300}{5}$

Solve.

Red=60

There are red cars in the parking lot.

$Red:250\rightarrow \frac{Red}{250}$

Now, we can create a proportion using our two ratios.

$\frac{1}{10}=\frac{Red}{250}$

Cross multiply and solve for Red .

$10 \times Red=1\times 250$

Simplify.

10 Red=250

Divide both sides of the equation by .

$\frac{10Red}{10}=\frac{250}{10}$
