EXAMPLE 1 Using a Model to Multiply Decimals Sloths The sloth is commonly referred to as the “slowest mammal on Earth.” Its top speed on the ground is about 0.2 mile per hour. To find the farthest a sloth might go in 0.6 hour, use a model to find

Draw a square. The whole square represents 1. The width of each row or column is 1 tenth, or 0.1. EXAMPLE 1 STEP 1 Using a Model to Multiply Decimals Sloths SOLUTION The sloth is commonly referred to as the “slowest mammal on Earth.” Its top speed on the ground is about 0.2 mile per hour. To find the farthest a sloth might go in 0.6 hour, use a model to find

EXAMPLE 1 STEP 2 Shade a rectangle. Each small square represents 1 hundredth, or The shaded area consists of 12 squares, or 12 hundredths. So, Using a Model to Multiply Decimals = 0.12.

EXAMPLE 1 STEP 2 Shade a rectangle. Each small square represents 1 hundredth, or The shaded area consists of 12 squares, or 12 hundredths. So, Using a Model to Multiply Decimals ANSWER The farthest a sloth might go in 0.6 hour is 0.12 mile = 0.12.

GUIDED PRACTICE for Example 1 Draw a model to find the product

GUIDED PRACTICE for Example 1 Draw a model to find the product. Draw a square. The whole square represents 1. The width of each row or column is 1 tenth, or 0.1. STEP 1 SOLUTION

STEP 2 Shade a rectangle. Each small square represents 1 hundredth, or The shaded area consists of 7 squares, or 7 hundredths. So, ANSWER GUIDED PRACTICE for Example = 0.07.
