Is a negative number a rational number?
Not necessarily. There are negative irrational numbers, such as negative pi, negative square root of 2, etc.. Some negative numbers that are rational include -2, -13, -8, -4/7, -241/39 etc.
Rational numbers greater than 1 but less than 2?
Any number that can be expressed as a fraction. When converted to decimal, they either give a finite number of places (e.g. 3/8 becomes 0.375) or give a recurring decimal (E.g. 1/3 becomes 0.333333...etc) Irrational numbers include pi, square root of 2 and e.
Can a pair of numbers have more than one common multiple or more than one common factor using a diagram to explain thinking?
All sets of numbers have an infinite number of common multiples. The set of common factors is finite, but can have more than one member. It is not possible to include a diagram in our answers,.
What is the greatest common factor of 33 55 and 77?
The factors of 33 include 1,3,11,33The factors of 55 include 1,5,11,55The factors of 77 include 1,7,11,77Therefore the greatest common factor of 33, 55 and 77 is 11.
The set of numbers that include the natural numbers their opposites and 0?
The set of numbers that include the natural numbers, their opposites and 0 is called the set of integers.
Can the domain of a function include an irrational number?
Yes. The domain and range can include irrational numbers.
What is the exact area of a circle with a diameter of 25 m?
The exact area is 625*pi. Since pi is an irrational number, any exact answer must include pi and may not contain a decimal (or rational) approximation of pi.
Can an irrational number include a square root that simplifies into an integer?
no
What is 6.6 round to the nearest hundredth?
The number 6.6 is already rounded to the nearest hundredth. If you wish to express this number and include hundredths, the number is equal to 6.60.
Can we include irrational numbers in the set of positive numbers?
Yes, any positive number is a number that doesn't have a (-) behind it (-20; -23.67; -45.45454...), and is not zero (0). Any repeating number (see 3rd negative example) is irrational, no matter what its sign. Irrational numbers also include numbers (decimals, specifically) that don't repeat, but don't stop. Numbers that don't terminate include pi. Pi, as it is, is proof of a positive irrational number.
2.799 rounded to nearest hundredth?
2.80 (include the zero to show to what place you rounded)
Is -8.0 rational or irrational?
-8.0 is a rational number. Irrational numbers are things such as numbers that can't be expressed as a fraction in the a/b form. Such numbers that are irrational include pi, square roots of negative numbers, etc.
What is 2.799 rounded to the nearest hundredth?
2.80
What is a word with the letters ir in?

Why the product of nonzero rational number and a rational number is an irrational?
Actually the product of a nonzero rational number and another rational number will always be rational.The product of a nonzero rational number and an IRrational number will always be irrational. (You have to include the "nonzero" caveat because zero times an irrational number is zero, which is rational)
Are all numbers rational?
no if yes, then why is there a term 'irrational numbers'? examples of irrational numbers include: sqrt(2), sqrt(3), sqrt (5), pi, e, 0.10100100010000010000001... etc.
Is fraction the densest subset of real numbers?
No. Fractions do not include irrational numbers. And although there are an infinite number of both rationals and irrationals, there are far more irrational numbers than rationals.
