Remember

 

If the divisor is in the tenths place, multiply it by ten to get a whole number.

0.5 x 10 = 5

If the divisor is in the hundredths place, multiply it by one hundred to get a whole number.

0.05 x 100 = 5

If the divisor is in the thousandths place, multiply it by one thousand to get a whole number.

0.005 x 1000 = 5
