Check the answer
Work backwards: 0.941176 × 51 = 48, which is 48 once rounding is allowed for.
Rounding
Rounded to a whole number the decimal is 1, to one decimal place 0.9 and to two decimal places 0.94. 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: 10/25 as a decimal
- Simplify: 10/25 = 2/5 (divide by 5)
- Divide the numerator by the denominator: 10 ÷ 25 = 0.4
Equivalent fractions
48/51 has the same value as 96/102, 144/153 and 480/510: multiplying the top and bottom by the same number never changes a fraction. All of them give 0.(9411764705882352) when divided out.
Comparing with nearby fractions
48/51 (0.9412) is bigger than 48/52 (0.9231) and smaller than 49/51 (0.9608). A bigger denominator means smaller pieces, so with the same numerator the fraction gets smaller.
The reciprocal
Flipping the fraction gives 51/48 = 1.0625. A number multiplied by its reciprocal is always 1: 48/51 × 51/48 = 1.
In time and money
48/51 of an hour is 56.47 minutes, and 48/51 of a day is 22.59 hours.
In a pie chart
A slice worth 48/51 of the whole takes up 338.82 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.
