The easiest way to solve problems involving "two unit multipliers" is to use a technique called unit conversion or dimensional analysis.
To solve such problems, you need to convert the given value from one unit to another by multiplying it by a series of conversion factors or unit multipliers. A conversion factor is a fraction that has the same value as one, but its numerator and denominator are expressed in different units.
For example, to convert 10 meters to feet, you can use the conversion factor:
1 meter = 3.28 feet
To convert 10 meters to feet, you would multiply 10 by the conversion factor:
10 meters * (3.28 feet/1 meter) = 32.8 feet
The meters unit cancels out, leaving you with the desired unit of feet.
In some cases, you may need to use multiple conversion factors to get from one unit to another. In these cases, you can multiply or divide the conversion factors to cancel out the unwanted units until you get to the desired unit.
Using unit conversion or dimensional analysis is an effective way to solve problems involving two unit multipliers because it ensures that the units cancel out correctly, and you end up with the desired unit in your final answer.
