How To Divide By A Fraction
Simplify the fraction if needed example.
How to divide by a fraction. Then flip the second fraction over so the bottom number of the second fraction is now on the top. Change the second fraction to its reciprocal. Multiply the top numbers of both fractions together to get the numerator top number of your new fraction. Then do the division.
Then multiply the two denominators. Turn the second fraction the one you want to divide by upside down this is now a reciprocal. 1 2 3. 2 1 4 equals 9 4.
You can also draw a diagram to help you visualize the process. There are 3 simple steps to divide fractions. Dividing fractions step by step examples. To divide fractions by fractions start by replacing the division sign with a multiplication sign.

Finally simplify the fractions if needed.
To divide one fraction by another fraction change the problem to multiplication. Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. Dividing fractions is as easy as pie. The first step to dividing fractions is to find the reciprocal reverse the numerator and denominator of the second fraction.
In fact after you change mixed numbers to improper fractions dividing fractions is just like multiplying fractions except that you flip the numerator and the denominator of the second fraction. Mathematicians didn t want to muck up fraction division by making you do something as complicated as actually dividing so they devised a way to use multiplication instead. The easiest way to do this is to convert the mixed number into an improper fraction. 9 4 3 3 4 your final answer.
The standard way of dividing a whole number by a fraction is to multiply the whole number by the reciprocal of the fraction. Next multiply the two numerators. Dividing fractions by a whole number isn t as hard as it looks.
