Dividing Fractions quicker when denominators are equal
I have to divide a fraction by a fraction. Normally, I need to ‘flip’ the divisor and then multiply. Is there a quicker or easier way to do it?
If the denominators are equal, there is. Just take the dividend’s numerator over the divisor’s numerator. Then simplify.
For instance, from out problem, 20/12 divided by 15/12 becomes 20/15. Then you can simplify both numerator by dividing by 5 to get 4/3, or 1 1/3. Done!
