Multiple Choice

What is the rule for measuring?

• Divide the part you want to know by the total amount. Than hit enter before multiplying by 100.

• Add up all of the pieces of data and hit enter on your calculator. Then, divide the number by the number of pieces of data.

• You should look to the right of the place value you are supposed to round to. If the number is 5 or greater, than you round up. If the number is 4 or smaller, then you round off.

• Your measurement should be one decimal place smaller than what each line (division) counts for. Your measurement should include a label.
