What is 68/88 as a Decimal?

68/88 = 0.7(72)

Step by step

  1. Simplify: 68/88 = 17/22 (divide by 4)
  2. Divide the numerator by the denominator: 68 ÷ 88 = 0.77272727
  3. The digits in brackets repeat forever: 0.7(72)

How the answer is worked out

A fraction is a division: 68/88 means 68 divided by 88, and doing that division gives 0.7(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, 68/88 is 77.2727%. 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 68/88 of a cup needs 0.773 cups, about 185.4545 millilitres.
  • Measuring: 68/88 of an inch is 0.7727 inches, or 19.63 millimetres.
  • Money: 68/88 of a dollar is about $0.77, and 68/88 of $100 is $77.27.

A quicker way

Long division: 88 goes into 68 0 times, remainder 68.

Bring down a zero: 680 ÷ 88 = 7, remainder 64.

Bring down a zero: 640 ÷ 88 = 7, remainder 24.

Bring down a zero: 240 ÷ 88 = 2, remainder 64.

The remainder 64 has come up before, so the digits from that point repeat forever: 0.7(72).

Check the answer

Work backwards: 0.772727 × 88 = 68, which is 68 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 0.77. 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: 14/9 as a decimal

  1. Simplify: 14/9 is already in simplest form
  2. Divide the numerator by the denominator: 14 ÷ 9 = 1.55555556
  3. The digits in brackets repeat forever: 1.(5)

Equivalent fractions

68/88 has the same value as 136/176, 204/264 and 680/880: multiplying the top and bottom by the same number never changes a fraction. All of them give 0.7(72) when divided out.

Comparing with nearby fractions

68/88 (0.7727) is bigger than 68/89 (0.764) and smaller than 69/88 (0.7841). A bigger denominator means smaller pieces, so with the same numerator the fraction gets smaller.

The reciprocal

Flipping the fraction gives 88/68 = 1.(2941176470588235). A number multiplied by its reciprocal is always 1: 68/88 × 88/68 = 1.

In time and money

68/88 of an hour is 46.36 minutes, and 68/88 of a day is 18.55 hours.

In a pie chart

A slice worth 68/88 of the whole takes up 278.18 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.
