The Highest Common Factor (HCF) between two numbers is the highest possible number that divides evenly to both numbers.
To simplify a fraction, divide the numerator and denominator by their HCF
Alternatively, we can use any common factor and keep dividing until we get the simplest form
28÷280÷2 |
= |
1440 |
Divide by 2 since they are both even |
Simplify the fraction further by again dividing 2
14÷240÷2 |
= |
720 |
Since this can no longer be simplified, 720 is the simplest fraction
