EQUIVALENT FRACTIONS Fraction that is worth the same as another fraction but looks different. Eg. 1 = Useful for canceling fractions(simplest form) and addition/subtraction.

How to change fractions (Do the same to top and bottom) x4 2 = x4

Top heavy or Improper Fractions Fractions which have a larger top (numerator) than bottom (denominator) Have a value of more than 1 Can switch from mixed number to top heavy fraction easily Useful for addition, subtraction, multiplication and division

Addition/Subtraction Denominators must be the same. Use equivalent fractions to change if necessary Check to see if your answer will simplify.

Change to top heavy Make denominators the same Subtract numerators 3 4

What about addition? Exactly the same process as subtraction but add instead.

How do we multiply? No. Not that sort of multiplying.

3 1 x Make into top heavy fractions 10 x Multiply across the top and then the bottom Cancel down your answer 5 10 =

What about division? The same as multiplication except……..

For one sneaky bit 1 2 / Change to top heavy fractions 5 / Instead of dividing, ‘flip’ the divisor and multiply 5 x 6 = Simplify by canceling 30 =

That’s all folks!
