All the ratios 25:5, 10:2, 5:1, and 15:3 are equivalent to each other.
Ratio:
Ratio is referred as the an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
Here we have the ratio 25:5 and 10:2 equivalent ratios to 5:1 and 15:3.
Basically, the equivalent ratios are calculated as by either dividing or multiply with some other real numbers in order to simplify it.
First, we have to take the ratio 25: 5,
When we simplify it by dividing the term by 5, then we get, 5:1.
So, the term 25: 5 is equivalent to 5:1.
Similarly, when we take 10:2 and then we simply divide it by 2, then we get 5:1.
So, both ratio are equivalent one with 5:1. But not associated with the other ratio 15:3.
But when we simplify 15:3 by dividing it using 3, then we get 5:1.
Therefore, all the ratios 25:5, 10:2, 5:1, and 15:3 are equivalent to each other.
