What you need to know
To achieve 100+ you need to:
add and subtract fractions with different denominators and mixed numbers, using the concept of equivalent fractions.
- Denominators in fractions need to be equal before they can be added or subtracted. Use equivalent fractions, which have the same value even though they look different (e.g.
= 
).
- Simplifying fractions involves dividing the numerator and denominator by a common factor.
