Rounding

Rounded to a whole number the decimal is 1, to one decimal place 0.6 and to two decimal places 0.57. 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: 12/8 as a decimal

  1. Simplify: 12/8 = 3/2 (divide by 4)
  2. Divide the numerator by the denominator: 12 ÷ 8 = 1.5

Equivalent fractions

55/97 has the same value as 110/194, 165/291 and 550/970: multiplying the top and bottom by the same number never changes a fraction. All of them give 0.567010309278350515463917525773195876288659793814432989690721 when divided out.

Comparing with nearby fractions
