Question

How many red squares will there be if there are 60 squares?

Answer 1

• There are 3 red squares.

,

• There are 4 white squares.

To compare them and get the ratio, we can build the following relation:

$\frac{3}{4}=\frac{x}{60}$

where x is the number of red squares it will be when there are 60 white squares.

Solving for x:

$x=\frac{3}{4}\cdot60$$x=45$

Answer: C. 45
