What is 34/2 as a Decimal?
34/2 = 17
Step by step
- Simplify: 34/2 = 17/1 (divide by 2)
- Divide the numerator by the denominator: 34 ÷ 2 = 17
How the answer is worked out
A fraction is a division: 34/2 means 34 divided by 2, and doing that division gives 17. The division ends after a few digits, because the simplified denominator has no prime factors other than 2 and 5.
As a percentage, 34/2 is 1,700%. It is an improper fraction: as a mixed number it is 17.
Why calculate this?
Decimals are easier to compare and to use in calculators and spreadsheets than fractions.
- Cooking: a recipe that asks for 34/2 of a cup needs 17 cups, about 4,080 millilitres.
- Measuring: 34/2 of an inch is 17 inches, or 431.8 millimetres.
- Money: 34/2 of a dollar is about $17, and 34/2 of $100 is $1,700.
A quicker way
The simplified denominator 1 divides 10, so scale the fraction up instead of dividing: 17/1 = 170/10 = 17.
Check the answer
Work backwards: 17 × 2 = 34, which is 34 once rounding is allowed for.
Rounding
Rounded to a whole number the decimal is 17, to one decimal place 17.0 and to two decimal places 17.00. 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: 7/63 as a decimal
- Simplify: 7/63 = 1/9 (divide by 7)
- Divide the numerator by the denominator: 7 ÷ 63 = 0.11111111
- The digits in brackets repeat forever: 0.(1)
Equivalent fractions
34/2 has the same value as 68/4, 102/6 and 340/20: multiplying the top and bottom by the same number never changes a fraction. All of them give 17 when divided out.
Comparing with nearby fractions
34/2 (17) is bigger than 34/3 (11.3333) and smaller than 35/2 (17.5). A bigger denominator means smaller pieces, so with the same numerator the fraction gets smaller.
The reciprocal
Flipping the fraction gives 2/34 = 0.(0588235294117647). A number multiplied by its reciprocal is always 1: 34/2 × 2/34 = 1.
In time and money
34/2 of an hour is 1,020 minutes, and 34/2 of a day is 408 hours.
In a pie chart
A slice worth 34/2 of the whole takes up 6,120 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.

Common mistakes
Dividing the denominator by the numerator flips the fraction. A bar over (or brackets around) digits means they repeat forever.
