Answer:
The answer is below
Step-by-step explanation:
A fraction is the ratio of the numerator to the denominator. It is given as:
Fraction = numerator / denominator.
If both the numerator and denominator are equal then:
numerator = denominator
Fraction = numerator / denominator = numerator / numerator = 1
When using fractions with units, if you want the units to be canceled out the both the numerator and the denominator must have the same units.
Because the numerator and denominator of the fraction are equivalent, the value of the fraction is 1. Multiplying by 1 does not change the quantity, but using an equivalence will change the units (or label) o In order for units to cancel they must be in both numerator and denominator of the fraction,
