- Divide the numerator by the denominator: 21 ÷ 96 = 0.21875
How the answer is worked out
A fraction is a division: 21/96 means 21 divided by 96, and doing that division gives 0.21875. The division ends after a few digits, because the simplified denominator has no prime factors other than 2 and 5.
As a percentage, 21/96 is 21.875%. It is a proper fraction, so its value is between 0 and 1, and it is less than one half.
Why calculate this?
Decimals are easier to compare and to use in calculators and spreadsheets than fractions.
- Cooking: a recipe that asks for 21/96 of a cup needs 0.219 cups, about 52.5 millilitres.
- Measuring: 21/96 of an inch is 0.2188 inches, or 5.56 millimetres.
- Money: 21/96 of a dollar is about $0.22, and 21/96 of $100 is $21.88.
A quicker way
The simplified denominator 32 divides 100000, so scale the fraction up instead of dividing: 7/32 = 21875/100000 = 0.21875.
Check the answer
Work backwards: 0.21875 × 96 = 21, which is 21 once rounding is allowed for.
Rounding
Rounded to a whole number the decimal is 0, to one decimal place 0.2 and to two decimal places 0.22. 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: 5/73 as a decimal
- Simplify: 5/73 is already in simplest form
- Divide the numerator by the denominator: 5 ÷ 73 = 0.06849315
- The digits in brackets repeat forever: 0.(06849315)
Equivalent fractions
21/96 has the same value as 42/192, 63/288 and 210/960: multiplying the top and bottom by the same number never changes a fraction. All of them give 0.21875 when divided out.
Comparing with nearby fractions
21/96 (0.2188) is bigger than 21/97 (0.2165) and smaller than 22/96 (0.2292). A bigger denominator means smaller pieces, so with the same numerator the fraction gets smaller.
The reciprocal
Flipping the fraction gives 96/21 = 4.(571428). A number multiplied by its reciprocal is always 1: 21/96 × 96/21 = 1.
In time and money
21/96 of an hour is 13.13 minutes, and 21/96 of a day is 5.25 hours.
In a pie chart
A slice worth 21/96 of the whole takes up 78.75 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.
