What is 88/80 as a Decimal?

88/80 = 1.1

Step by step

  1. Simplify: 88/80 = 11/10 (divide by 8)
  2. Divide the numerator by the denominator: 88 ÷ 80 = 1.1

How the answer is worked out

A fraction is a division: 88/80 means 88 divided by 80, and doing that division gives 1.1. The division ends after a few digits, because the simplified denominator has no prime factors other than 2 and 5.

As a percentage, 88/80 is 110%. It is an improper fraction: as a mixed number it is 1 1/10.

Why calculate this?

Decimals are easier to compare and to use in calculators and spreadsheets than fractions.

  • Cooking: a recipe that asks for 88/80 of a cup needs 1.1 cups, about 264 millilitres.
  • Measuring: 88/80 of an inch is 1.1 inches, or 27.94 millimetres.
  • Money: 88/80 of a dollar is about $1.1, and 88/80 of $100 is $110.

A quicker way

The simplified denominator 10 divides 10, so scale the fraction up instead of dividing: 11/10 = 11/10 = 1.1.

Check the answer

Work backwards: 1.1 × 80 = 88, which is 88 once rounding is allowed for.

Rounding

Rounded to a whole number the decimal is 1, to one decimal place 1.1 and to two decimal places 1.10. 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: 17/72 as a decimal

  1. Simplify: 17/72 is already in simplest form
  2. Divide the numerator by the denominator: 17 ÷ 72 = 0.23611111
  3. The digits in brackets repeat forever: 0.236(1)

Equivalent fractions

88/80 has the same value as 176/160, 264/240 and 880/800: multiplying the top and bottom by the same number never changes a fraction. All of them give 1.1 when divided out.

Comparing with nearby fractions

88/80 (1.1) is bigger than 88/81 (1.0864) and smaller than 89/80 (1.1125). A bigger denominator means smaller pieces, so with the same numerator the fraction gets smaller.

The reciprocal

Flipping the fraction gives 80/88 = 0.(90). A number multiplied by its reciprocal is always 1: 88/80 × 80/88 = 1.

In time and money

88/80 of an hour is 66 minutes, and 88/80 of a day is 26.4 hours.

In a pie chart

A slice worth 88/80 of the whole takes up 396 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.

Doing it in a spreadsheet

In Excel, Google Sheets or Numbers type =88/80 into any cell. Replace the numbers with cell references (for example A1 and B1) to reuse the formula for a whole column.

Common mistakes

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