• Rewrite a decimal as a mixed number.

• Add three decimals where one is a whole number, one goes to the tenths’ place and one goes to

• the hundredths’ place (23 + 0.8 + 0.05)

• Add a fraction whose denominator is a power of ten to a decimal.

• Subtract decimals.

• Multiply a decimal by a power of ten.

• Multiply two decimals. Locate the answer “between” two given whole numbers.

• Write a percent as a decimal.

• Write a percent as a fraction.

• Know that “__ percent of __” means to multiply.

• Know that “twice as big” means 200%, “three times as big” means 300%, etc.

• “Reverse percents” (If 60 is 25% of a number, then the number is what percent of 60?)

• Solve all three types of percent problems:

• Find a percentage of a number (Find 20% of 65)

• Find the number when a percentage is given (34 is 5% of what number?)

• Find the percent (8 is what percent of 12?)
