KS3 Maths - 23. Working with Fractions (Converting, improper, adding, multiplying)

Working with fractions reminds me of PIZZA.

+ or -  fractions   = common denominator (Bottom number)

Reducing means simplifying - are any of the umbers divisible by another number?

x fractions = x top, x bottom (no need for common denominator).

Improper (top heavy_ i.e. 9/2) conversions to mixed fractions  = divide
Mixed fractions to improper fractions = x    11/2 = 3/2

I get it.

It always helps to look at other sources when you learning something  new:
