Rounding

Rounded to a whole number the decimal is 1, to one decimal place 0.9 and to two decimal places 0.91. 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: 9/73 as a decimal

  1. Simplify: 9/73 is already in simplest form
  2. Divide the numerator by the denominator: 9 ÷ 73 = 0.12328767
  3. The digits in brackets repeat forever: 0.(12328767)

Equivalent fractions

43/47 has the same value as 86/94, 129/141 and 430/470: multiplying the top and bottom by the same number never changes a fraction. All of them give 0.(9148936170212765957446808510638297872340425531) when divided out.

Comparing with nearby fractions

43/47 (0.9149) is bigger than 43/48 (0.8958) and smaller than 44/47 (0.9362). A bigger denominator means smaller pieces, so with the same numerator the fraction gets smaller.

The reciprocal
