Question

Naomi learned: “To multiply a whole number by ten, just place a zero at the end of the number.” For example, 5961×10, she says, is 59,610. She does not understand why this rule is true.

Explain why the rule Naomi learned is true. (Use any connections you can make after completing Part A.)

Answer 1

Answer/explanation:

the rule is true because every number can be expressed as a decimal, and multiplying the number by 10 moves the decimal ONE place to the right.

example:

5961 in decimal form is 5961.0

multiply 5,961.0 by 10 and the decimal point moves one place to the right.

5,961.0 turns into 59,610.0
