**ABOUT PROPORTIONS:**A proportion occurs when two ratios are forced to be equal to each other. This selection will allow you to find a second ratio that is in the same proportion as the first. Since a ratio is made up of two numbers, and a proportion compares

**2**ratios, we ’ ll be dealing with 4 numbers here, 2 for each ratio.

- The first ratio will be between the two numbers represented by a and b. As a ratio, it will be
**a to b**, or**a:b**. You can choose numbers for a and b below. - The second ratio will be between the two numbers represented by c and d. As a ratio, it will be
**c to d**, or**c:d**. You can choose numbers for c and d below.

**a:b::c:d**, or in fractional form as a/b=c/d
