what is the difference between an irrational number and a integer?
PLZ HELP ME!!!
a rational number is what you know as a fraction. It is the ratio of two whole numbers.
3/4, -7/11, etc.
An integer is a rational number with a denominator of 1. Or, more commonly just what you think of as a counting number, but may be negative:
3/1 = 3
-2/1 = -2
and so on
An irrational number cannot be expressed as a fraction. When written down as a decimal, they never terminate, so a decimal value is not exact. There are various kinds of irrational numbers, such as
√2 = 1.414...
e = 2.71828...
π = 3.14159...
∛17 = 2.57128...
The special symbols used on the left give their exact values. The decimal equivalents are just an approximation.
Dear everyone telling ppl not to cheat:
a lot of the people here, myself included, don't really care if we learn anything. the goal is to pass, not to learn at this point. Also if you know anything about the public school system, the objective is never for us to 'learn', it's for them to shove a bunch of knowledge down our throats and then we put it down onto whatever paper or screen they give us. no one is here to be shamed for trying to pass.
