Exercise 8 Page 49

We want to find the given product. - 1 56 * 6 12 Before evaluate the expression, will rewrite the mixed numbers as fractions. When multiply real numbers, the product of an integer a by an integer b is always positive if those integers have the same sign. cc Same Sign & Different Signs (+)(+)=(+) & (+)(-)=(-) (-)(-)=(+) & (-)(+)=(-) In our case one number is positive and one number is negative, so the product will be negative. 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 product!
