Which ratios form of proportion use equivalent ratios to test each pair
The ratios that form a proportion use equivalent ratios to test each pair. A proportion is an equation that states that two ratios are equal. In other words, if we have two ratios, a/b and c/d, they form a proportion if and only if ad = bc.
To test if two ratios form a proportion, we can use equivalent ratios. Equivalent ratios are ratios that have the same value but may have different numbers. We can find equivalent ratios by multiplying or dividing both the numerator and denominator of a given ratio by the same number.
For example, let's say we have the ratio 2/3 and we want to test if it forms a proportion with the ratio 4/6. We can find equivalent ratios by multiplying both the numerator and denominator of the first ratio by 2.
2/3 * 2/2 = 4/6
Now, we can compare the two ratios:
2/3 = 4/6
Since the two ratios are equal, we can conclude that they form a proportion.
In this way, we can use equivalent ratios to test if two ratios form a proportion.
