What decimal is equavilent to 78?
78 is a whole number so it is more than one. Decimals deal with the numbers between whole numbers. So its like having 78 dollars with no change. So 78.00.
What are the consequences of using radical fuctions?
Assuming you mean radical functions, the answer is that you can work with problems that deal with irrational numbers. The classic one was finding the diagonal of a unit square.
What are irrational and rational numbers?
Rational numbers are any numbers that can be expressed as a fraction. For example 1/3, 1/2, and 2. Irrational numbers are numbers that can not be expressed as a fraction. Some examples are Pi, the square root of 2, and e. Both rational and irrational numbers are real numbers. Unlike imaginary numbers like the square root of -1.An irrational number is a number that can't be expressed by a fraction having integers in both its numerator and denominator. A rational number can be.Rational and irrational numbers are both subsets of real numbers, together they make up the set of what we call real numbers.If you have trouble remembering which is which, just think of rational numbers as fractions, or numbers that can be written as a/b where a and b are integers. Remember that b can equal 1 so [2 = 2/1]. Therefore all integers, as well as whole and natural numbers are also rational numbers.Irrational numbers are real numbers that are not rational. One way that people describe Irrational is the answer goes on and on forever and does not have a repeating pattern. Two classic examples are Pi (3.14159...), and the base of the natural log e (2.7128...).Rational, when expressed in decimal form, can stop (terminate) at a certain point or it may have a pattern of digits which repeats forever. An example of a rational that repeats is 1/3. Certainly it is written as a/b with a and b both being integers, but its decimal representation is 0.333.... where in this case the dots mean that the (3) repeats forever.There is a hierarchy of numbers and understanding it sometimes helps remember and understand the differences.At the top of the hierarchy are the complex numbers. Next come the real numbers and then then rational numbers. Next comes the integers, then the whole numbers and last the natural numbers.An irrational number is a number that can't be expressed by a fraction having integers in both its numerator and denominator. A rational number can be.
When comparing fractions and square roots it is best to use your calculuator to find the decimal number?
Fne if they are sufficiently far apart. Otherwise, you may be better off squaring all the numbers. The smaller numbers will still have the smaller squares and at least you won't have irrational numbers to deal with.
How whole numbers integers rational numbers and irrational numbers came?
When pre-historical people started counting - their friends (or members in their "gang"), their enemies, the numbers of prey animals or how many days away there was water or good hunting - they counted in integers. That was fine until they needed to share things. And that is when ratios or rational numbers came in. However, once they started studying mathematics - geometry in particular - they found that some problems could not be solved using rational numbers. For example, if you had a square with unit sides, its diagonal could not be rational. A circle with unit radius did not have a unit circumference. Irrational numbers were introduced to deal with this shortcoming.
