Exercise 6 Page 143

When multiplying real numbers, the product will be positive if the signs are the same and it will be negative if the signs are different. cc Same Sign & Different Signs (+)(+)=(+) & (+)(-)=(-) (-)(-)=(+) & (-)(+)=(-)In our case one number is positive and one number is negative, so the product will be negative. 8/3 * (- 2 12 ) = - 8/3 * 2 12 Now, notice that one number is a fraction and the other is a mixed number. Before we evaluate the expression, let's first rewrite the second number as a fraction.

- 8/3 * 2 12

Recall that 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!
