That's the second driest on the books, behind May 1964 when only 0.09 inches fell in the Lehigh Valley. For the year so far, the Valley had only 11 inches of rain â down from the normal 16 inches. It doesn't help that temperatures are creeping up. The average temperature this month is 65.4 degrees â 6 degrees above normal. It's been a very warm and dry month, Meola said.
Rational numbers sound like they should be very sensible numbers. In fact, they are. Rational numbers are simply numbers that can be written as fractions or ratios (this tells you where the term rational comes from). The hierarchy of real numbers looks something like this:
The Integers. The integers are the set of real numbers consisting of the natural numbers, their additive inverses and zero. {..., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5...}. The set of integers is sometimes written J or Z for short.The sum, product, and difference of any two integers is also an integer.he Rational Numbers. The rational numbers are those numbers which can be expressed as a ratio between two integers. For example, the fractions 1/3 and â1111/8 are both rational numbers. All the integers are included in the rational numbers, since any integer z can be written as the ratio z /1.
