Exercise 6 Page 65

Multiply as though they were both whole numbers. Place the decimal point in the product by counting the number of decimal places in each factor.

8.014

Practice makes perfect

Before we find the exact product, we can estimate the multiplication by rounding the decimal numbers. Only the first factor is a decimal. We will round 2.0035 to 2 because it is the closest whole number. 2 * 4 = 8The product of 2.0035 and 42 is about 8. To find the product, we multiply just as we do with two whole numbers. At first, we ignore any decimal points. We should also make sure that the partial products are aligned in the correct place values.

$20035 \times 4 = 80140$

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

placing the decimal point

The product of 2.0035 and 4 is 8.0140, or simply 8.014. This is pretty close to our estimate of 8!
