Exercise 2 Page 98

We want to find the following product. 85 * 0.25 * 3 First, let's use the Commutative Property of Multiplication and rearrange two last terms. This will allow us to calculate the product of two whole numbers first.

To find the product of a whole number and a decimal, we multiply just as we do with two whole numbers. At first, we ignore any decimal points.

Then we place the decimal point in the product by counting the number of decimal places in each factor.

The product of 85, 0.25, and 3 is 63.75.
