Answer:
45 x (1/3) = 15
Explanation:
Note that when you divide with a fraction, you will change the division into multiplication, and flip the second term. In this case:
15/(1/3) = 15 * 3 = 45
In the answer's case, when you multiply a fraction, you are really multiplying the term with the numerator, and then dividing the denominator:
(45 x 1)/3 = 45/3 = 15
