To find what percentage one number is of another; divide the first number by the other number and multiply by 100. For example, four is 50 percent of eight because four divided by eight is 1/2. One-half multiplied by 100 is 50.You also do this to divide real numbers. Think about dividing a bag of 26 marbles into two smaller bags with the same number of marbles in each. You can also say each smaller bag has one half of the marbles. 26÷2 = 26(1 2)= 13 26 ÷ 2 = 26 ( 1 2) = 13. Notice that 2 and 1 2 1 2 are reciprocals. A real x is represented by a sequence q(0),q(1),… of rational numbers that approximates x in the sense that for any degree of accuracy ε there exists some natural number n such that for all k > n, |q(k) − x| < ɛ A real number is a computable real number if there is an algorithm that allows us to compute an approximation to the number to any given degree …20 abr 2011 ... > > letters and numbers appear completely over each other.
