Why calculate this?

Decimals are easier to compare and to use in calculators and spreadsheets than fractions.

  • Cooking: a recipe that asks for 25/23 of a cup needs 1.087 cups, about 260.8696 millilitres.
  • Measuring: 25/23 of an inch is 1.087 inches, or 27.61 millimetres.
  • Money: 25/23 of a dollar is about $1.09, and 25/23 of $100 is $108.7.

A quicker way

Long division: 23 goes into 25 1 time, remainder 2.

Bring down a zero: 20 ÷ 23 = 0, remainder 20.

Bring down a zero: 200 ÷ 23 = 8, remainder 16.

Bring down a zero: 160 ÷ 23 = 6, remainder 22.

Bring down a zero: 220 ÷ 23 = 9, remainder 13.

Bring down a zero: 130 ÷ 23 = 5, remainder 15.

Keep going until a remainder repeats; from then on the digits repeat as well.

Check the answer

Work backwards: 1.086957 × 23 = 25, which is 25 once rounding is allowed for.

Rounding

Rounded to a whole number the decimal is 1, to one decimal place 1.1 and to two decimal places 1.09. 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: 5/38 as a decimal

  1. Simplify: 5/38 is already in simplest form
  2. Divide the numerator by the denominator: 5 ÷ 38 = 0.13157895
  3. The digits in brackets repeat forever: 0.1(315789473684210526)

Equivalent fractions

25/23 has the same value as 50/46, 75/69 and 250/230: multiplying the top and bottom by the same number never changes a fraction. All of them give 1.(0869565217391304347826) when divided out.

Comparing with nearby fractions

25/23 (1.087) is bigger than 25/24 (1.0417) and smaller than 26/23 (1.1304). A bigger denominator means smaller pieces, so with the same numerator the fraction gets smaller.

The reciprocal

Flipping the fraction gives 23/25 = 0.92. A number multiplied by its reciprocal is always 1: 25/23 × 23/25 = 1.

In time and money

25/23 of an hour is 65.22 minutes, and 25/23 of a day is 26.09 hours.

In a pie chart

A slice worth 25/23 of the whole takes up 391.3 degrees of the circle, because a full turn is 360 degrees. That is the angle to draw when you make the chart by hand with a protractor.
