This activity is about dividing a fraction by a fraction.
To divide a fraction by another fraction, we can use the KFC method.
No, not the yummy chicken and chips method - but nearly as much fun!!
Keep the first fraction
Flip the second fraction
Change the ÷ to a ×
Once we have done this, we multiply the fractions as we normally would by multiplying the numerators, and multiplying the denominators.
Examples
3 | ÷ | 1 | = | 3 | x | 4 | = | 12 | ||
5 | 4 | 5 | 1 | 5 | ||||||
4 | ÷ | 2 | = | 4 | x | 7 | = | 28 | = | 14 |
3 | 7 | 3 | 2 | 3 |
NB Answers in this activity should be given as reduced fractions.
Leave fractions as top-heavy, but write integers as whole numbers (i.e. 5 not 5/1)
