Exercise 19 Page 47

Before we evaluate the expression, let's first rewrite it so that all of the numbers are fractions. The quotient of 1 and 8 59 is the same as the quotient of 11 and 779. 1 ÷ 8 59 &= 1/1 ÷ 77/9 &= * &= Now, dividing fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. Knowing this, we can fill the second box. 1 ÷ 8 59 &= 1/1 ÷ 77/9 &= 1/1 * 9/77 &= Now, when multiplying fractions, remember that the product of two fractions is equal to the product of the numerators over the product of the denominators.
