How many positive integers less than 100 have reciprocals with terminating decimal representation?
To determine how many positive integers less than 100 have reciprocals with terminating decimal representation, we need to consider the prime factorization of each integer. Any positive integer whose prime factorization consists only of 2s and/or 5s will have a reciprocal with a terminating decimal representation. In the range of positive integers less than 100, there are 49 numbers that are powers of 2, 5, or their products (2^0, 2^1, 2^2, ..., 2^6, 5^0, 5^1, 5^2). Therefore, there are 49 positive integers less than 100 with reciprocals having terminating decimal representations.
Well, honey, let me break it down for you. The positive integers with reciprocals that have a terminating decimal representation are the ones that only have 2 and 5 as prime factors in their denominator. So, you just need to count how many numbers less than 100 can be expressed as 2^a * 5^b where a and b are non-negative integers. And the answer is 40.
Oh, dude, this is like a math riddle or something. So, you know how reciprocals with terminating decimal representations are like 1/2 or 1/4, right? Well, those are like fractions with powers of 2 in the denominator. So, you just gotta count how many positive integers less than 100 have only 2s and 5s in their prime factorization. I mean, it's not rocket science, but it's kinda fun to figure out.

Are all integers positive?
The set of integers includes negative integers as well as positive integers. It also includes the number zero which is neither negative nor positive.
Which set best represents the positive integers?
The set of positive integers, of course!
What is a Non-negative integers?
They are simply positive integers
Integers greater than zero are what kind of integers?
These are positive integers, usually denoted with the symbol (+) the number. Check the video on youtube Ordering Integers.
How do you figure out negative exponents?
They are the reciprocals of the positive exponents. Thus, x-a = 1/xa

What are non positive integers?
Non-positive integers are zero and the negative integers.
Are all whole numbers positive numbers?
Yes, EXCEPT for the number 0. It is a whole number but is not positive or negative. Real Numbers - Everything I. Rational Numbers- Any number except for non terminating decimals A. Integers- Any negative or positive number...not a decimal1. Whole Numbers- Any positive integer INCLUDING ZEROa. Natural Numbers- Any positive integer (NOT INCLUDING ZERO) The answer is not entirely correct, Whole numbers are numbers without a fractional part or decimal point. Therefore whole numbers can be negative as well as positive. -2 is a whole number but is not positive. There are a number of different interpretations for whole numbers, from non-negative integers, positive integers and all integers (which includes negative integers)
When the negative integers the positive integers and 0 are combined the integers are formed?
Negative integers, zero and the positive integers, together form the set of integers.

Are 0 0.25 and 2.6 positive integers?
No, none of them are positive integers.
What is b and a if both are positive integers but a does not equal b?

Give example of closure property?
Add two positive integers and you ALWAYS have a positive integers. The positive integers are closed under addition.
How do divide integers?
* The quotient of two positive integers or two negative integers is positive. * The quotient of a positive integer and a negetive integer is negetive.
Another name for the positive integers?
