What is 100/48 as a Decimal?
100/48 = 2.08(3)
Step by step
- Simplify: 100/48 = 25/12 (divide by 4)
- Divide the numerator by the denominator: 100 ÷ 48 = 2.08333333
- The digits in brackets repeat forever: 2.08(3)
How the answer is worked out
A fraction is a division: 100/48 means 100 divided by 48, and doing that division gives 2.08(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, 100/48 is 208.3333%. It is an improper fraction: as a mixed number it is 2 1/12.
Why calculate this?
Decimals are easier to compare and to use in calculators and spreadsheets than fractions.
- Cooking: a recipe that asks for 100/48 of a cup needs 2.083 cups, about 500 millilitres.
- Measuring: 100/48 of an inch is 2.0833 inches, or 52.92 millimetres.
- Money: 100/48 of a dollar is about $2.08, and 100/48 of $100 is $208.33.
A quicker way
Long division: 48 goes into 100 2 times, remainder 4.
Bring down a zero: 40 ÷ 48 = 0, remainder 40.
Bring down a zero: 400 ÷ 48 = 8, remainder 16.
Bring down a zero: 160 ÷ 48 = 3, remainder 16.
The remainder 16 has come up before, so the digits from that point repeat forever: 2.08(3).
Check the answer
Work backwards: 2.083333 × 48 = 100, which is 100 once rounding is allowed for.
Rounding
Rounded to a whole number the decimal is 2, to one decimal place 2.1 and to two decimal places 2.08. 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: 19/33 as a decimal
- Simplify: 19/33 is already in simplest form
- Divide the numerator by the denominator: 19 ÷ 33 = 0.57575758
- The digits in brackets repeat forever: 0.(57)
Equivalent fractions
100/48 has the same value as 200/96, 300/144 and 1000/480: multiplying the top and bottom by the same number never changes a fraction. All of them give 2.08(3) when divided out.
Comparing with nearby fractions
100/48 (2.0833) is bigger than 100/49 (2.0408) and smaller than 101/48 (2.1042). A bigger denominator means smaller pieces, so with the same numerator the fraction gets smaller.
The reciprocal
Flipping the fraction gives 48/100 = 0.48. A number multiplied by its reciprocal is always 1: 100/48 × 48/100 = 1.
In time and money
100/48 of an hour is 125 minutes, and 100/48 of a day is 50 hours.
In a pie chart
A slice worth 100/48 of the whole takes up 750 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.
