1. Fractions

   • Adding and Subracting
     • Denominator has to be the same.
       • Just add/take-away the tops, then leave the denominator the same.
   • Multiplying and Dividing
     • Denominator does NOT have to be the same.
       • Multiplication: just multiply both top and bottom, then simplify if can and asked.
       • Division: see if you can cancel out any like terms and flip the second fraction, and then multiply!

2. Ratio

   • Similar to fractions - they can be simplified by finding the highest common factor and dividing by that number.
     • For example : The ratio to girls and boys is 15:12 - both these numbers are a in the 3 times table so we divide by 3 and get : 5:4
