EXAMPLE 1 Using a Model to Multiply Decimals

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 0. 6. might go in 0. 6 hour, use a model to find 0. 2

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 0. 6. might go in 0. 6 hour, use a model to find 0. 2 SOLUTION STEP 1 Draw a 10 10 square. The whole square represents 1. The width of each row or column is 1 tenth, or 0. 1.

EXAMPLE 1 Using a Model to Multiply Decimals STEP 2 Shade a 0. 2 0. 6 rectangle. Each small square represents 1 hundredth, or 0. 01. The shaded area consists of 12 squares, or 12 hundredths. So, 0. 2 0. 6 = 0. 12.

EXAMPLE 1 Using a Model to Multiply Decimals STEP 2 Shade a 0. 2 0. 6 rectangle. Each small square represents 1 hundredth, or 0. 01. The shaded area consists of 12 squares, or 12 hundredths. So, 0. 2 0. 6 = 0. 12. ANSWER The farthest a sloth might go in 0. 6 hour is 0. 12 mile.

GUIDED PRACTICE for Example 1 Draw a model to find the product. 1. 0. 1 0. 7

GUIDED PRACTICE for Example 1 Draw a model to find the product. 1. 0. 1 0. 7 SOLUTION STEP 1 Draw a 10 10 square. The whole square represents 1. The width of each row or column is 1 tenth, or 0. 1.

GUIDED PRACTICE for Example 1 STEP 2 Shade a 0. 1 0. 7 rectangle. Each small square represents 1 hundredth, or 0. 01. The shaded area consists of 7 squares, or 7 hundredths. So, 0. 1 0. 7 = 0. 07. ANSWER 0. 07

GUIDED PRACTICE 2. 0. 3 0. 8 for Example 1

GUIDED PRACTICE 2. 0. 3 for Example 1 0. 8 SOLUTION STEP 1 Draw a 10 10 square. The whole square represents 1. The width of each row or column is 1 tenth, or 0. 1.

GUIDED PRACTICE for Example 1 STEP 2 Shade a 0. 3 0. 8 rectangle. Each small square represents 1 hundredth, or 0. 01. The shaded area consists of 24 squares, or 24 hundredths. So, 0. 3 0. 8 = 0. 24. ANSWER 0. 24

GUIDED PRACTICE 3. 0. 9 0. 7 for Example 1

GUIDED PRACTICE 3. 0. 9 for Example 1 0. 7 SOLUTION STEP 1 Draw a 10 10 square. The whole square represents 1. The width of each row or column is 1 tenth, or 0. 1.

GUIDED PRACTICE for Example 1 STEP 2 Shade a 0. 9 0. 7 rectangle. Each small square represents 1 hundredth, or 0. 01. The shaded area consists of 63 squares, or 63 hundredths. So, 0. 9 0. 7 = 0. 63. ANSWER 0. 63
