Rounding
  • There are plenty more activities in Section 3
    Decimals
  • In exam questions, look very carefully to see
    what you are asked to round to. Marks are easily
    lost by not reading the question
  • Remember money should always be to two decimal
    places.
  • e.g.6.50 not 6.5 or 6.503
