2. Data:
Present knowledge of facts contained in such an example as .0027 divided by .05.
3. Inferences:
(a) The divisor (.05) may be converted into a whole number by multiplying it by 100.
(b) If the divisor is multiplied by 100, the dividend must also be multiplied by 100 if the quotient is to be unchanged.
(c) The problem thus becomes .27 divided by 5, for which the answer is .054.
4. Verification:
Check the work to see that no mistakes have been made in the calculation. Multiply the quotient by the divisor to see if the result is equal to the dividend.
