This educational guide outlines efficient strategies for performing multiplication and division with decimals by converting them into simpler whole-number problems. To solve multiplication tasks, the text instructs students to calculate the product as if the decimals were absent before reinserting the decimal point based on the total count of decimal places in the original values. For division problems, the resource suggests formatting the expression as a fraction and scaling both the numerator and denominator by powers of ten to remove any fractional components from the divisor.
