The Rhind Mathematical Papyrus. An Egyptian fraction is a finite sum of distinct unit fractions, such as That is, each fraction in the expression has a numerator equal to 1 and a denominator that is a positive integer, and all the denominators differ from each other. The value of an expression of this type is a positive rational number ; for ...
[3] Ray J's 1997 debut single, " Let It Go ", was released by EastWest Records for the soundtrack to the F. Gary Gray film, Set It Off . Both moderate hits, the song peaked within the top 40 of the Billboard Hot 100 and additionally served as the lead single for Ray J's debut studio album, Everything You Want (1997), which entered the Top R&B ...
As an illustration of this, the parity cycle (1 1 0 0 1 1 0 0) and its sub-cycle (1 1 0 0) are associated to the same fraction 5 / 7 when reduced to lowest terms. In this context, assuming the validity of the Collatz conjecture implies that (1 0) and (0 1) are the only parity cycles generated by positive whole numbers (1 and 2 ...
Apple AirPods (2nd Generation) $80 $129 Save $49. This is an outrageous price for AirPods! In fact, it's a record-low price, so if you've been toying with a pair or need to replace your current ...
A fraction 3 / y requires three terms in its greedy expansion if and only if y ≡ 1 (mod 6), for then −y mod x = 2 and y(y + 2) / 3 is odd, so the fraction remaining after a single step of the greedy expansion, () ⌈ ⌉ = (+) is in simplest terms. The simplest fraction 3 / y with a three-term expansion is 3 / 7 .
In the mathematics of sums of powers, it is an open problem to characterize the numbers that can be expressed as a sum of three cubes of integers, allowing both positive and negative cubes in the sum. A necessary condition for an integer to equal such a sum is that cannot equal 4 or 5 modulo 9, because the cubes modulo 9 are 0, 1, and −1, and ...
The probability of drawing another gold coin from the same box is 0 in (a), and 1 in (b) and (c). Thus, the overall probability of drawing a gold coin in the second draw is 0 / 3 + 1 / 3 + 1 / 3 = 2 / 3 . The problem can be reframed by describing the boxes as each having one drawer on each of two sides. Each ...
Every terminating decimal representation can be written as a decimal fraction, a fraction whose denominator is a power of 10 (e.g. 1.585 = 1585 / 1000 ); it may also be written as a ratio of the form k / 2 n ·5 m (e.g. 1.585 = 317 / 2 3 ·5 2 ).
