Exercise 28 Page 317

When we multiply fractions, we need to remember that the product of two fractions is equal to the product of the numerators divided by the product of the denominators. Let's find the given product! 1 13/14 * 25/12= 1 13 * 25/14 * 12 Now we have a product of fractions in the numerator and in the denominator. Let's find each of these products one by one.

1 13 * 2/5

Now, let's rewrite our expression using the found products. 1 13 * 25/14 * 12 = 815/18 Finally, recall that the quotient of two fractions is a product of the fraction in the numerator and the reciprocal of the fraction in the denominator. 815/1 8 = 8/15 * 8/1 Finally, let's find the resulting product!
