The original ratio is given to be:
The question asks to write the ratio in the form:
This means that we have to divide both sides of the ratio by the 2nd ratio (2.25). This is because we have the 2nd part of the ratio n:1 to be 1. This will give us the new ratio.
Therefore, the new ratio can be calculated to be:
Therefore, the new ratio in the form of n : 1 is given to be:
