Carpenters need to know how to divide fractions for some calculations. For example, carpenters may have to divide fractions when laying out stairs or deciding how much material was used.
To divide fractions, begin by changing mixed numbers to improper fractions. Next, use the rule of keep-change-flip. Keep the first fraction, change the sign from division to multiplication, and then flip (invert) the second fraction. To complete the operation, reduce numerators and denominators to lowest terms. Multiply the numerators and the denominators. Convert the improper fraction to a mixed number. Check the number for lowest terms.
