What is 31/93 as a Decimal?
31/93 = 0.(3)
Step by step
- Simplify: 31/93 = 1/3 (divide by 31)
- Divide the numerator by the denominator: 31 ÷ 93 = 0.33333333
- The digits in brackets repeat forever: 0.(3)
How the answer is worked out
A fraction is a division: 31/93 means 31 divided by 93, and doing that division gives 0.(3). The division never ends, because the simplified denominator has a prime factor other than 2 or 5. The digits in brackets repeat forever.
As a percentage, 31/93 is 33.3333%. 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 31/93 of a cup needs 0.333 cups, about 80 millilitres.
- Measuring: 31/93 of an inch is 0.3333 inches, or 8.47 millimetres.
- Money: 31/93 of a dollar is about $0.33, and 31/93 of $100 is $33.33.
A quicker way
Long division: 93 goes into 31 0 times, remainder 31.
Bring down a zero: 310 ÷ 93 = 3, remainder 31.
The remainder 31 has come up before, so the digits from that point repeat forever: 0.(3).
Check the answer
Work backwards: 0.333333 × 93 = 31, which is 31 once rounding is allowed for.
Rounding
Rounded to a whole number the decimal is 0, to one decimal place 0.3 and to two decimal places 0.33. 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: 7/35 as a decimal
- Simplify: 7/35 = 1/5 (divide by 7)
- Divide the numerator by the denominator: 7 ÷ 35 = 0.2
Equivalent fractions
31/93 has the same value as 62/186, 93/279 and 310/930: multiplying the top and bottom by the same number never changes a fraction. All of them give 0.(3) when divided out.
Comparing with nearby fractions
31/93 (0.3333) is bigger than 31/94 (0.3298) and smaller than 32/93 (0.3441). A bigger denominator means smaller pieces, so with the same numerator the fraction gets smaller.
The reciprocal
Flipping the fraction gives 93/31 = 3. A number multiplied by its reciprocal is always 1: 31/93 × 93/31 = 1.
In time and money
31/93 of an hour is 20 minutes, and 31/93 of a day is 8 hours.
In a pie chart
A slice worth 31/93 of the whole takes up 120 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.
