Rounding

Rounded to a whole number the decimal is 1, to one decimal place 0.6 and to two decimal places 0.59. Round only at the end: rounding halfway through a calculation can change the last digit.

The formula explained

decimal = numerator ÷ denominator. The numerator is the top number and counts the pieces; the denominator is the bottom number and says how many equal pieces make a whole. Dividing the top by the bottom gives the size of the fraction as a decimal.

Another worked example: 12/11 as a decimal

  1. Simplify: 12/11 is already in simplest form
  2. Divide the numerator by the denominator: 12 ÷ 11 = 1.09090909
  3. The digits in brackets repeat forever: 1.(09)

Equivalent fractions

57/97 has the same value as 114/194, 171/291 and 570/970: multiplying the top and bottom by the same number never changes a fraction. All of them give 0.587628865979381443298969072164948453608247422680412371134020 when divided out.

Comparing with nearby fractions
