WebNow, we cross multiply fractions to find the numerators. First, we multiply the numerator of the first fraction with the denominator of the second fraction. 3 × 8 = 24. So, the first fraction becomes: 24 56. Next, we multiply the second fraction’s numerator by the first fraction’s denominator. 5 × 7 = 35. WebWe multiply the numerators to find the numerator of the product, and then multiply the denominators to find the denominator of the product. Before multiplying, it is helpful to factor the numerators and denominators just as we did when simplifying rational expressions. We are often able to simplify the product of rational expressions. WebDividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.
