Is the quotient of two nonzero numbers never a rational number?
The quotient of two nonzero integers is the definition of a rational number. There are nonzero numbers other than integers (imaginary, rational non-integers) that the quotient of would not be a rational number. If the two nonzero numbers are rational themselves, then the quotient will be rational. (For example, 4 divided by 2 is 2: all of those numbers are rational).
Which of the following sets of numbers contains multiplicative inverses for all its nonzero elements?
Please don't write "the following" if you don't provide a list. This is the situation for some common number sets:* Whole numbers / integers do NOT have this property. * Rational numbers DO have this property. * Real numbers DO have this property. * Complex numbers DO have this property. * The set of non-negative rational numbers, as well as the set of non-negative real numbers, DO have this property.
Are all negative rational numbers integers?
No, they are not because fractions can be negative also. fractions aren't integers
How many significant digits are in 1581.7812?
Eight - all nonzero integers are significant.
Does the commutative property of addition apply when you add to negative integers?
Yes. The commutative property of addition (as well as the commutative property of multiplication) applies to all real numbers, and even to complex numbers. As an example (for integers): 5 + (-3) = (-3) + 5
Is some whole numbers are not integers?
No. All whole numbers are integers and all integers are whole numbers.
What is the factor of all numbers?
One is a factor of all nonzero numbers.
How many significant figures are in 789?
Three. All nonzero integers are significant.
What type of numbers are always significant?
All nonzero numbers are significant.
Are some integers not rational numbers?
All integers are rational numbers. There are integers with an i behind them that are imaginary numbers. They are not real numbers but they are rational. The square root of 2 is irrational. It is real but irrational.
Are some real number integers?
All integers are real numbers, but not all real numbers are integers.
Are all real numbers integers?
No, all integers are real numbers, but not all real numbers are integers. For example, 1.25 is a real number and a non-integer.No.
