Dividing Decimal Numbers

The video tutorial explains how to solve division problems involving decimals using visual aids like grids. It starts with a deli worker's problem of dividing ham into slices and demonstrates using grids to visualize the division. Another example involves estimating miles per gallon for a car trip using compatible numbers. The tutorial concludes with tips on solving division problems using different methods and emphasizes the importance of checking answers.

How many slices of ham did the deli worker cut if each slice weighs 0.5 ounces and the total weight is 4.5 ounces?

• 10 slices

• 9 slices

• 8 slices

• 11 slices

What is the purpose of using grids in solving division problems with decimals?

• To increase the number of steps

• To avoid using numbers

• To visually represent the division process

• To make the problem more complex

If the Martin family drove 247.8 miles using 11.2 gallons of gasoline, what is the estimated miles per gallon using compatible numbers?

• 18 miles per gallon

• 22 miles per gallon

• 15 miles per gallon

• 20 miles per gallon

Why are compatible numbers used in division problems?

• To increase the number of calculations

• To simplify the division process

• To avoid rounding numbers

• To make division more difficult

What should you do if you get different answers using different methods for a division problem?

• Re-evaluate the methods and calculations

• Use a calculator to verify

• Ignore the discrepancy

• Choose the answer you like best
