What are the basic and right rules for dividing fractions?
FRACTION RULES Multiplying and Dividing Fractions: 1. Common denominators are NOT needed. 2. Always change mixed numbers to improper fractions. 3. CANCEL (reduce) between any numerator and any denominator if you can, but cancel only when a multiplication sign is present: Never cancel when you have a division sign. 4.
How do you divide fractions step by step?
Try another example!
- First divide the numerator by the denominator, ( 24/10 = 2 remainder 4 ).
- Write the answer out as 2 4/10. ...
- Note that 4 and 10 are both even numbers, so the first step in reducing them is to divide them each by 2. ...
How to find a reciprocal of a fraction?
