Dividing Decimals LESSON 1 9 Additional Examples Course

Dividing Decimals LESSON 1 -9 Additional Examples Course 1 A class of 27 students held a picnic. They purchased food and drinks for the picnic for a total cost of $93. 15. What was the price for each student’s meal? Since you are looking for prices of equal meals, you need to divide. Estimate 93. 15 ÷ 27 90 ÷ 30, or 3 3. 45 Divide as with whole numbers. Place the 27 93. 15 decimal point in the quotient above the – 81 decimal point in the dividend. 12 1 – 10 8 13 5 – 13 5 Each student’s meal cost $3. 45. 0 Check for Reasonableness 3. 45 is reasonable since it close to 3.

Dividing Decimals LESSON 1 -9 Course 1 Additional Examples Find each quotient. a. 0. 475 ÷ 0. 05 0. 475 Since the divisor has two decimal places, multiply the dividend and the divisor by 100 so that the divisor is a whole number. 9. 5 5 47. 5 – 45 25 – 25 0 Now divide as with whole numbers. Place the decimal point in the quotient above the decimal point in the dividend.

(continued) b. 9. 674 ÷ 0. 7 9. 674 Since the divisor has one decimal place, multiply the dividend and the divisor by 10 so that the divisor is a whole number. 13. 82 7 96. 74 – 7 26 – 21 57 – 56 14 – 14 0 Now divide as with whole numbers. Place the decimal point in the quotient above the decimal point in the dividend.
