What is 75/99 as a Decimal?
75/99 = 0.(75)
Step by step
- Simplify: 75/99 = 25/33 (divide by 3)
- Divide the numerator by the denominator: 75 ÷ 99 = 0.75757576
- The digits in brackets repeat forever: 0.(75)
How the answer is worked out
A fraction is a division: 75/99 means 75 divided by 99, and doing that division gives 0.(75). 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, 75/99 is 75.7576%. It is a proper fraction, so its value is between 0 and 1, and it is more 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 75/99 of a cup needs 0.758 cups, about 181.8182 millilitres.
- Measuring: 75/99 of an inch is 0.7576 inches, or 19.24 millimetres.
- Money: 75/99 of a dollar is about $0.76, and 75/99 of $100 is $75.76.
A quicker way
Long division: 99 goes into 75 0 times, remainder 75.
Bring down a zero: 750 ÷ 99 = 7, remainder 57.
Bring down a zero: 570 ÷ 99 = 5, remainder 75.
The remainder 75 has come up before, so the digits from that point repeat forever: 0.(75).
Check the answer
Work backwards: 0.757576 × 99 = 75, which is 75 once rounding is allowed for.
Rounding
Rounded to a whole number the decimal is 1, to one decimal place 0.8 and to two decimal places 0.76. 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: 15/67 as a decimal
- Simplify: 15/67 is already in simplest form
- Divide the numerator by the denominator: 15 ÷ 67 = 0.2238806
- The digits in brackets repeat forever: 0.(223880597014925373134328358208955)
Equivalent fractions
75/99 has the same value as 150/198, 225/297 and 750/990: multiplying the top and bottom by the same number never changes a fraction. All of them give 0.(75) when divided out.
Comparing with nearby fractions
75/99 (0.7576) is bigger than 75/100 (0.75) and smaller than 76/99 (0.7677). A bigger denominator means smaller pieces, so with the same numerator the fraction gets smaller.
The reciprocal
Flipping the fraction gives 99/75 = 1.32. A number multiplied by its reciprocal is always 1: 75/99 × 99/75 = 1.
In time and money
75/99 of an hour is 45.45 minutes, and 75/99 of a day is 18.18 hours.
In a pie chart
A slice worth 75/99 of the whole takes up 272.73 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.
