How do you divide fractions?
Zanzabum
2/8 divided by 1/4. Steps: 1. Division in math actually means multiplication. You just have to multiply by the reciprocal of the second fraction (reciprocal= denominator and numerator are switched). 2. Do 2/8 times 4/1. 3. 2 times 4= 8 and 8 times 1= 8 4. Your answer would be 8/8 which equals 1. This is how you divide fractions
