Formula for dividing two fractions

\[{a \over b} \div {c \over d} = {ad \over bc} \]

Frazer says "To divide a fraction by another fraction, follow these three easy steps."

Frazer the Fraction Salamander

Step 1

If any of the fractions are mixed fractions, then first convert them into improper fractions.

Invert (swap) the numerator and denominator of the dividend fraction (the fraction after the ÷ sign) and change the operand to a 'x' instead of a '÷' .

Step 2

Multiply the numerators and denominators of the fractions together, This will give you the answer.

You should have now found your fraction of a number!

Step 3 - optional

You may want to convert the fraction into its simplest form and/or convert it back to a mixed fraction (if it is an improper fraction).

How to Divide Fractions Examples

Example 1) Calculate   \[{3 \over 5} ÷ {2 \over 7} \]

Step 1)

\[{3 \over 5} ÷ {2 \over 7} = {3 \over 5} \times {7 \over 2}\]

Step 2)

\[{3 \over 5} \times {7 \over 2} = {3 \times 7 \over 5 \times 2} = {21 \over 10}\]

Step 3)

Answer in simplest form is: \[{21 \over 10} \; or \; 2 {1 \over 10}\]

Final answer: \[{3 \over 5} ÷ {2 \over 7} \; = \; {21 \over 10} \; or \; 2 {1 \over 10}\]

Example 2) Calculate   \[{9 \over 4} ÷ {3 \over 5} \]

Step 1)

\[{9 \over 4} ÷ {3 \over 5} = {9 \over 4} \times {5 \over 3}\]

Step 2)

\[{9 \over 4} \times {5 \over 3} = {9 \times 5 \over 4 \times 3} = {45 \over 12}\]

Step 3)

Simplify Answer: \[{45 \over 12} \; = \; {15 \over 4} \; or \; 3 {3 \over 4}\]

Final answer: \[{9 \over 4} ÷ {3 \over 5} \; = \; {15 \over 4} \; or \; 3 {3 \over 4}\]

Example 3) Calculate   \[{4 \over 7} ÷ {1 \over 3} \]

Step 1)

\[{4 \over 7} ÷ {1 \over 3} = {4 \over 7} \times {3 \over 1}\]

Step 2)

\[{4 \over 7} \times {3 \over 1} = {4 \times 3 \over 7 \times 1} = {12 \over 7}\]

Step 3)

Answer in simplest form is: \[{12 \over 7} \; or \; 1 {5 \over 7}\]

Final answer: \[{4 \over 7} ÷ {1 \over 3} \; = \; {12 \over 7} \; or \; 1 {5 \over 7}\]
