Question: multiplying by 1/3 is the same as?
Answer: We'll switch the numerator and the denominator of the fraction we're dividing by: 1/3 in this example. So 1/3 becomes 3/1. This is called finding the reciprocal, or multiplicative inverse, of the fraction. Since we're switching our original fraction, we'll also switch the division sign (÷) to a multiplication sign (x).
