Countdown to Exams - Day 27 - Fractions - Multiplying and Dividing
On day 27 we continue calculating with fractions focusing on Multiplying and Dividing fractions. Unlike addition and subtraction there is no need to have a common denominator if we are asked to multiply/ divide fractions. All you need to do is multiply numerators, multiply denominators, simplify your answer. When dividing fractions you need to flip the second fraction and multiply. (Keep Change Flip)
Always look to see if you can cross cancel first. This will mean that you don't have to multiply large complicated numbers. When faced with mixed numbers, look to convert to improper fractions first.
The processes required to multiply and divide fractions are covered by Matt in the video below.
