Practice: Dividing a Decimal by a Decimal

You CAN NOT have a decimal in the divisor.

If the divisor has a decimal, you must multiply the divisor by a power of 10 to make it a whole number.

Then you must multiply the dividend by the same power of 10.

Examples:

 $17.52\ \div\ 1.52\ \ ->\ 1,752\ \div\ 152$
