What is 80/27 as a Decimal?
80/27 = 2.(962)
Step by step
- Simplify: 80/27 is already in simplest form
- Divide the numerator by the denominator: 80 ÷ 27 = 2.96296296
- The digits in brackets repeat forever: 2.(962)
How the answer is worked out
A fraction is a division: 80/27 means 80 divided by 27, and doing that division gives 2.(962). 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, 80/27 is 296.2963%. It is an improper fraction: as a mixed number it is 2 26/27.
Why calculate this?
Decimals are easier to compare and to use in calculators and spreadsheets than fractions.
- Cooking: a recipe that asks for 80/27 of a cup needs 2.963 cups, about 711.1111 millilitres.
- Measuring: 80/27 of an inch is 2.963 inches, or 75.26 millimetres.
- Money: 80/27 of a dollar is about $2.96, and 80/27 of $100 is $296.3.
A quicker way
Long division: 27 goes into 80 2 times, remainder 26.
Bring down a zero: 260 ÷ 27 = 9, remainder 17.
Bring down a zero: 170 ÷ 27 = 6, remainder 8.
Bring down a zero: 80 ÷ 27 = 2, remainder 26.
The remainder 26 has come up before, so the digits from that point repeat forever: 2.(962).
Check the answer
Work backwards: 2.962963 × 27 = 80, which is 80 once rounding is allowed for.
Rounding
Rounded to a whole number the decimal is 3, to one decimal place 3.0 and to two decimal places 2.96. 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: 15/39 as a decimal
- Simplify: 15/39 = 5/13 (divide by 3)
- Divide the numerator by the denominator: 15 ÷ 39 = 0.38461538
- The digits in brackets repeat forever: 0.(384615)
Equivalent fractions
80/27 has the same value as 160/54, 240/81 and 800/270: multiplying the top and bottom by the same number never changes a fraction. All of them give 2.(962) when divided out.
Comparing with nearby fractions
80/27 (2.963) is bigger than 80/28 (2.8571) and smaller than 81/27 (3). A bigger denominator means smaller pieces, so with the same numerator the fraction gets smaller.
The reciprocal
Flipping the fraction gives 27/80 = 0.3375. A number multiplied by its reciprocal is always 1: 80/27 × 27/80 = 1.
In time and money
80/27 of an hour is 177.78 minutes, and 80/27 of a day is 71.11 hours.
In a pie chart
A slice worth 80/27 of the whole takes up 1,066.67 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.
