Wednesday, Oct 16 Lesson 3.8 Divide Decimals by Decimals

12
Objective: To understand how to estimate and divide decimals by decimals.

13
Divide Decimals by Decimals When dividing a decimal by a decimal, change the divisor to a whole number. To do this, move the decimal in both the divisor and dividend to the right. Then divide as before.

14
Divide Decimals by Decimals Find 1.71÷ 0.9 Estimate?

15
Divide Decimals by Decimals Find 1.71÷ 0.9 Estimate? 2 ÷ 1 = 2

16
Divide Decimals by Decimals Find 1.71÷ 0.9 Divide a decimal by a decimal. Step 1 – Place the numbers in the dividing bracket. 0.9)1.71

17
Divide Decimals by Decimals Find 1.71÷ 0.9 To Divide a decimal by a decimal Step 2 – Move the decimal point to the right in both numbers so the divisor is a whole number. 09.)17.1

18
Divide Decimals by Decimals Find 1.71÷ 0.9 = 1.9 To Divide a decimal by a decimal Step 3 – Divide as before. You can drop decimal point and the zero in front of the divisor. 1.9 9 )17.1 -9 81 -81 00

31
Divide Decimals by Decimals Find 8.424 ÷ 0.36 Estimate? Remember – you can not 8 ÷ 0.5 = 16 divide by 0. Actual quotient?

32
Divide Decimals by Decimals Find 8.424 ÷ 0.36 = 23.4 23.4 0.36)8.424 = 36)842.4 -72 122 -108 144 -144 000 36, 72, 108, 144, 180, 216, 252

33
Divide Decimals by Decimals Find 0.009 ÷ 0.18 Estimate?

34
Divide Decimals by Decimals Find 0.009 ÷ 0.18 Estimate? Since both numbers are close to zero, the estimate would be zero. Actual quotient?
