What is 85/11 as a Decimal?
85/11 = 7.(72)
Step by step
- Simplify: 85/11 is already in simplest form
- Divide the numerator by the denominator: 85 ÷ 11 = 7.72727273
- The digits in brackets repeat forever: 7.(72)
How the answer is worked out
A fraction is a division: 85/11 means 85 divided by 11, and doing that division gives 7.(72). 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, 85/11 is 772.7273%. It is an improper fraction: as a mixed number it is 7 8/11.
Why calculate this?
Decimals are easier to compare and to use in calculators and spreadsheets than fractions.
- Cooking: a recipe that asks for 85/11 of a cup needs 7.727 cups, about 1,854.5455 millilitres.
- Measuring: 85/11 of an inch is 7.7273 inches, or 196.27 millimetres.
- Money: 85/11 of a dollar is about $7.73, and 85/11 of $100 is $772.73.
A quicker way
Long division: 11 goes into 85 7 times, remainder 8.
Bring down a zero: 80 ÷ 11 = 7, remainder 3.
Bring down a zero: 30 ÷ 11 = 2, remainder 8.
The remainder 8 has come up before, so the digits from that point repeat forever: 7.(72).
Check the answer
Work backwards: 7.727273 × 11 = 85, which is 85 once rounding is allowed for.
Rounding
Rounded to a whole number the decimal is 8, to one decimal place 7.7 and to two decimal places 7.73. 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: 16/6 as a decimal
- Simplify: 16/6 = 8/3 (divide by 2)
- Divide the numerator by the denominator: 16 ÷ 6 = 2.66666667
- The digits in brackets repeat forever: 2.(6)
Equivalent fractions
85/11 has the same value as 170/22, 255/33 and 850/110: multiplying the top and bottom by the same number never changes a fraction. All of them give 7.(72) when divided out.
Comparing with nearby fractions
85/11 (7.7273) is bigger than 85/12 (7.0833) and smaller than 86/11 (7.8182). A bigger denominator means smaller pieces, so with the same numerator the fraction gets smaller.
The reciprocal
Flipping the fraction gives 11/85 = 0.1(2941176470588235). A number multiplied by its reciprocal is always 1: 85/11 × 11/85 = 1.
In time and money
85/11 of an hour is 463.64 minutes, and 85/11 of a day is 185.45 hours.
In a pie chart
A slice worth 85/11 of the whole takes up 2,781.82 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.
