In general, a common fraction is said to be a proper fraction, if the absolute value of the fraction is strictly less than one—that is, if the fraction is greater than −1 and less than 1. [14] [15] It is said to be an improper fraction, or sometimes top-heavy fraction, [16] if the absolute value of the fraction is greater than or equal to 1 ...
For example, 1 / 4 , 5 / 6 , and −101 / 100 are all irreducible fractions. On the other hand, 2 / 4 is reducible since it is equal in value to 1 / 2 , and the numerator of 1 / 2 is less than the numerator of 2 / 4 . A fraction that is reducible can be reduced by dividing both the numerator ...
Slices of approximately 1/8 of a pizza. A unit fraction is a positive fraction with one as its numerator, 1/ n. ... greater than one, or less than one respectively. ...
Fibonacci applies the algebraic identity above to each these two parts, producing the expansion 8 / 11 = 1 / 2 + 1 / 22 + 1 / 6 + 1 / 66 . Fibonacci describes similar methods for denominators that are two or three less than a number with many factors.
Then the triangle is in Euclidean space if the sum of the reciprocals of p, q, and r equals 1, spherical space if that sum is greater than 1, and hyperbolic space if the sum is less than 1. A harmonic divisor number is a positive integer whose divisors have a harmonic mean that is an integer. The first five of these are 1, 6, 28, 140, and 270.
where c 1 = 1 / a 1 , c 2 = a 1 / a 2 , c 3 = a 2 / a 1 a 3 , and in general c n+1 = 1 / a n+1 c n . Second, if none of the partial denominators b i are zero we can use a similar procedure to choose another sequence {d i} to make each partial denominator a 1:
At the end of a long day, taking inventory of the fridge, cracking a cookbook open, or running out to the grocery store in order to figure out a dinner plan can seem overwhelming.
For instance, the golden ratio = (+) / = is a reduced surd because it is greater than one and its conjugate () / = is greater than −1 and less than zero. On the other hand, the square root of two 2 = ( 0 + 8 ) / 2 {\displaystyle {\sqrt {2}}=(0+{\sqrt {8}})/2} is greater than one but is not a reduced surd because its conjugate − 2 = ( 0 − ...
