    Problems 1–6 compute divisions of a certain number of loaves of bread by 10 men and record the outcome in unit fractions. Problems 7–20 show how to multiply the expressions 1 + 1/2 + 1/4 = 7/4, and 1 + 2/3 + 1/3 = 2 by different fractions. Problems 21–23 are problems in completion, which in modern notation are simply subtraction problems.

    This adds up to the total of ⁠ 1 / 3 ⁠ of the time (⁠ 1 / 6 ⁠ + ⁠ 1 / 6 ⁠) A is being pardoned, which is accurate. It is now clear that if the warden answers B to A (⁠ 1 / 2 ⁠ of all cases), then ⁠ 1 / 3 ⁠ of the time C is pardoned and A will still be executed (case 4), and only ⁠ 1 / 6 ⁠ of the time A is pardoned (case

  6. Mediant (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Mediant_(mathematics)

    However, if the fraction 1/1 is replaced by the fraction 2/2, which is an equivalent fraction denoting the same rational number 1, the mediant of the fractions 2/2 and 1/2 is 3/4. For a stronger connection to rational numbers the fractions may be required to be reduced to lowest terms , thereby selecting unique representatives from the ...

    If the ratio consists of only two values, it can be represented as a fraction, in particular as a decimal fraction. For example, older televisions have a 4:3 aspect ratio, which means that the width is 4/3 of the height (this can also be expressed as 1.33:1 or just 1.33 rounded to two decimal places). More recent widescreen TVs have a 16:9 ...
