Divide Rational Numbers Worksheet

6 problems

To divide rational numbers, the reciprocal of the second fraction is multiplied by the first fraction. By switching the second fraction's numerator and denominator, the reciprocal can be obtained. If you can, simplify the resulting fraction.

As an example, to divide \frac{2}{3} by  \frac{4}{5}.

\frac{2}{3} \times \frac{5}{4} = \frac{2 \times 5}{3 \times 4} = \frac{10}{12}, which simplifies to \frac{5}{6}. As an example, to divide \frac{2}{3} by \frac{4}{5}.

Solved Example

Q. Divide. $\newline$$\frac{5}{8}\div\frac{1}{4}=$_____
Solution:
1. Divide and Multiply: What is the multiplication form of $\frac{5}{8} \div \frac{1}{4}$?$\newline$Dividing by a number is the same as multiplying by its reciprocal.$\newline$$\frac{5}{8} \div \frac{1}{4} = \frac{5}{8} \times \frac{4}{1} = \left(\frac{5 \times 4}{8 \times 1}\right)$$= \frac{20}{8}$
2. Simplify Fraction: Simplify the fraction $\frac{20}{8}$. $\newline$$\frac{20}{8}$ can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is $4$. $\newline$$20 \div 4 = 5$ $\newline$$8 \div 4 = 2$ $\newline$So, $\frac{20}{8}$ simplifies to $\frac{5}{2}$.
