Question:

The ratio of girls girls to boys boys at a movie is 6:7. If there are 28 boys boys​, how many girls girls are at the​ movie?

Answer:

There are 24 girls at the​ movie.

Step-by-step explanation:

Given:

The ratio of girls to boys = 6:7

Number of boys  = 28

To Find:

Number of Girls at the movie = ?

Solution:

The Ratio of girls to boys = 6:7

girls : boys = 6 : 7

girls : 28 = 6 : 7

$\frac{girls}{28} = \frac{6}{7}$

Now by cross multiplication

$7 \times girls = 6 \times 28$

$7 \times girls = 168$

$girls = \frac{168}{7}$

girls  = 24
