Explanation:
What is a ratio?
A ratio has two or more numbers that symbolize relation to each other. Ratios are used to compare numbers, and you can compare them using division.
To solve for n, we can use this equation:
The new ratio is 2: 0.8
Why do we divide by 5?
We divide by 5 because in order to go from 10 to 2 (10: 4, 2: n) we divide the 10 by 5.
Therefore, the value of n is 0.8.
