What is 38/80 as a Decimal?
38/80 = 0.475
Step by step

- Divide the numerator by the denominator: 38 ÷ 80 = 0.475
How the answer is worked out
A fraction is a division: 38/80 means 38 divided by 80, and doing that division gives 0.475. The division ends after a few digits, because the simplified denominator has no prime factors other than 2 and 5.
As a percentage, 38/80 is 47.5%. 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 38/80 of a cup needs 0.475 cups, about 114 millilitres.
- Measuring: 38/80 of an inch is 0.475 inches, or 12.06 millimetres.
- Money: 38/80 of a dollar is about $0.47, and 38/80 of $100 is $47.5.
A quicker way
The simplified denominator 40 divides 1000, so scale the fraction up instead of dividing: 19/40 = 475/1000 = 0.475.
Check the answer
Work backwards: 0.475 × 80 = 38, which is 38 once rounding is allowed for.
Rounding
Rounded to a whole number the decimal is 0, to one decimal place 0.5 and to two decimal places 0.47. 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: 8/56 as a decimal
- Simplify: 8/56 = 1/7 (divide by 8)
- Divide the numerator by the denominator: 8 ÷ 56 = 0.14285714
- The digits in brackets repeat forever: 0.(142857)
Equivalent fractions
38/80 has the same value as 76/160, 114/240 and 380/800: multiplying the top and bottom by the same number never changes a fraction. All of them give 0.475 when divided out.
Comparing with nearby fractions
38/80 (0.475) is bigger than 38/81 (0.4691) and smaller than 39/80 (0.4875). A bigger denominator means smaller pieces, so with the same numerator the fraction gets smaller.
The reciprocal
Flipping the fraction gives 80/38 = 2.(105263157894736842). A number multiplied by its reciprocal is always 1: 38/80 × 80/38 = 1.
In time and money
38/80 of an hour is 28.5 minutes, and 38/80 of a day is 11.4 hours.
In a pie chart
A slice worth 38/80 of the whole takes up 171 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.
