Skill: Divide multiples of 10 by a 1-digit number

Explanation and Free Practice Resources

The learner understands that dividing a multiple of 10 by a one-digit divisor can be reduced to a basic fact and then restored through place value: $60 \div 3$ corresponds to $6 \div 3=2$ , so the quotient is 20. This reasoning applies to exact whole-number quotients for familiar multiples of 10, including numbers such as 120 or 420, and does not include decimal quotients, extended long division, or more advanced remainder cases.

Detailed Explanation: Divide multiples of 10 by a 1-digit number

To divide a multiple of $10$ by a 1-digit number:

Ignore the zero for a moment.
Divide the remaining number.
Put the zero back in the quotient.

Example:

120 \div 3

First, remove the zero from $120$ :

12 \div 3 = 4

Now put the zero back:

120 \div 3 = 40

So, the answer is:

\boxed{40}

Check: $40 \times 3 = 120$ , so the answer is correct.
