CONFIDENTIAL3 When multiplying a decimal by a decimal, multiply as with whole numbers. To place the decimal point, find the sum of the number of decimal places in each factor. The product has the same number of decimal places. Let’s review what we learned last time!

CONFIDENTIAL4 Divide a decimal by a 1-digit number Dividing a decimal by a whole number is similar to dividing whole numbers

CONFIDENTIAL5 Dividing decimals by a 1-digit number Example-1 Find 6.8 ÷ 2 = Estimate 6 ÷ 2 = Place the decimal point directly above the decimal point in the dividend. Divide as with whole numbers 6.8 ÷ 2 = 3.4. Compared to the estimate, the quotient is reasonable.

CONFIDENTIAL6 Example Divide 45.9 ÷ 3 Estimate 48 ÷ 3 = 16. Place the decimal point Divide as with whole numbers 45.9 ÷ 3 = Compared to estimate, quotient is reasonable. 15.3

CONFIDENTIAL7 Example Find 3.49 ÷ 4 Place the decimal point Annex a zero and continue dividing ÷ 4 = Compared to the estimate, the quotient is reasonable. Estimate is 4 ÷4 =
