Students learn to find equal ratios by first writing the given ratio as a fraction, then multiplying the numerator and denominator of the fraction by the same number. For example, to find two ratios that are equal to 1:7, first write 1:7 as the fraction 1/7. Next, multiply both the numerator and denominator of 1/7 by 2, to get 2/14, or 2:14, and multiply the numerator and denominator of 1/7 by 3, to get 3/21, or 3:21. So 2:14 and 3:21 are two ratios that are equal to 1:7. Students are also asked to determine whether two given ratios are equal, by first writing each ratio as a fraction, then writing each fraction in lowest terms. If the two fractions are the same when written in lowest terms, then the ratios are equal.
1224 = 1224/1 or 12240/10.
Ratios that are equal to each other can be 3/4=75/100 or 1/4=25/100
They are called equivalent ratios.
An equation that states that two ratios are equal is a proportion.

1 to 7 is already a ratio, another ratios is 1:7 or 1/7
the ratios of 28 and 7 is 25%
11/1 and -11/(-1) are two examples.
50 to 70 and 55 to 77 are two examples.
the simplest one is 3:1
They are: 10 to 14 and 15 to 21
12 to 14 18 to 21
15/1 and 150/10 are two such.
They are: 30/14 and 45/21
7/15 = 14/30 = 70/150
7 to 2 and 21 to 3
