Find the reciprocal of -2.
reciprocal means interchanging numerator and denominator here it's-2/1 understand after reciprocal denominator came upside so, it will be -1/2
Which of the following is the reciprocal of the reciprocal of a rational number?
The reciprocal of the reciprocal of a rational number is the number itself.
For example, Consider the rational no. 1/2. It's reciprocal is 2 and the reciprocal of 2 is 1/2. Therefore, it's the number itself.
What is the additive inverse of -2/3?
Additive inverse of a number is the number who when added to initial number sums up to zero.
If x is a negative number, then its additive inverse is equal and opposite in sign to it. This means that the additive inverse of a negative number is positive.
Hence, additive inverse of -2/3 is 2/3
So option C is the correct answer.
Find the multiplicative inverse of -13.
In order to find the multiplicative inverse of the given number, find the reciprocal of that number.
Here the given number is -13
So the reciprocal of -13 will be -1/13
Therefore, option C is the correct answer.
Which of the following is the reciprocal of a rational number?
Clearly, we can see that -1 and 1 are the numbers whose reciprocal is the number itself.
Which of the following statements is true?
Every rational number is not a fraction.
In rational numbers, we use integers and in fractions, we use only natural numbers.
For any three rational numbers a, b and c, a + (b + c) = __________.
It is the associative property and we know that the rational numbers are associative under addition.
For eg: 5/3 + (3/2 + 1/3) = 7/2;
(5/3 + 3/2) + 1/3 = 7/2
Here, Option 'a' is the correct answer.
Therefore, a+(b+c) = (a+b)+c
Which of the following is the Multiplicative identity for rational numbers?
1 is the multiplicative identity for rational numbers, natural numbers, integers.
Which of the following is the product of (-7/8) and 4/21?
-7 / 8 x 4 / 21 = - 1 / 6
So option A is the correct answer.
Which of the following is the identity element under addition?
Zero is called the identity for the addition of rational numbers.
Example: 2/3 + 0 = 2/3
