How would you find 1/10 of the baker's total cost for 100 pounds of chocolate sprinkles?
To find 1/10 of this total cost:
Take the total cost of $80.00.
Multiply by 1/10 (or divide by 10):
80.00÷10=8.0080.00 \div 10 = 8.0080.00÷10=8.00Therefore, 1/10 of the baker's total cost for 100 pounds of chocolate sprinkles is $8.00.

Explain how you would calculate the cost of 20 pounds of sugar at $0.80 per pound.
Multiply the number of pounds by the price per pound:

How can you explain the division of decimals to a classmate using examples?
Decimal by Whole Number: Just divide as usual, and place the decimal in the quotient directly above its position in the dividend.
Decimal by Decimal: Move the decimal in the divisor to make it a whole number. Move the decimal in the dividend the same number of places, then divide.
If Remainder: Bring down the next digit, or add zeroes if needed, and keep dividing.
