Rounding Mixed Numbers to Nearest Whole Number

Method:
  1. Look at the following mixed fractions.
  2. Approximate the fractional part to the nearest whole number.
  3. Add that to the whole number
  4. Note: In a mixed number 4 1/2 means 4 + 1/2 and not 4 x 1/2
Example: 4 3/4 - Round the fractional part.
  1. (Numerator) 3 is more than half of 4 (denominator), and hence greater than half of 4.
  2. 3/4 approximated as 1.
  3. Hence the mixed number is approximated as 4 + 1 = 5.
