1 to 32 to 6262 to 756There are an infinite more of them.
6.25:1.25 = 5:1 =15:3=10:2
2.5:1
no, 3 and 1/3 is equal to 33/10!
5,5, and 4
10 to 100, 2 to 20, 156 to 1560 are three examples.
15/1 and 150/10 are two such.
A true proportion is when two ratios are equal to one another. To prove this, you need to find the cross products of the ratios and see if they are equal. An example of a true proportion are the ratios 1/2 and 5/10, if you take the cross product the result is 2 x 5 = 1 x 10, which are equal.

To determine if the ratios ( \frac{2}{1} ) and ( \frac{20}{10} ) form a proportion, we can compare their cross products. The cross products are ( 2 \times 10 = 20 ) and ( 1 \times 20 = 20 ). Since both cross products are equal, the ratios do form a proportion.
