How do you divide fractions?

• A. Flip the second fraction and then multiply
• B. Find a common denominator
• C. Multiply numerators and denominators
• D. Take the reciprocal of the first fraction and multiply

Answer: (A)

Dividing fractions is done by multiplying by the reciprocal of the divisor. When you divide a fraction by another fraction, you multiply by the flipped second fraction. In notation, (a/b) ÷ (c/d) = (a/b) × (d/c).

For example, 3/4 ÷ 2/5 = 3/4 × 5/2 = 15/8. Flipping the second fraction and then multiplying follows this exact rule.

Other methods don’t fit: finding a common denominator is used for adding or subtracting fractions, not dividing; multiplying numerators and denominators alone would be the rule for multiplying fractions, not dividing; taking the reciprocal of the first fraction and multiplying would not generally yield the correct result because you must reciprocate the divisor, not the dividend.
