the side length of the state flag of Colorado are in the ratio of 2:3 if the flag is 12 ft long what is the height?​
yanalaym [24]

Answer:

The height is 8

Step-by-step explanation:

Ratios are just fractions. That being said, you also have part of a fraction. You know that the colorado flag is in 2:3, and 12 feet long is according to that ratio; it equals each other.

Make the equation.

\frac{2}{3}  = \frac{x}{12}

Now isolate x (in order to solve for it)

12 * \frac{2}{3}  = \frac{x}{12}*12\\8 = x

x= 8

The height is 8.

8/12 = 2/3 ✅
