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.
Expressing in standard form, we get
Express each rational number with L.C.M as denominator. L.C.M of 9 and 5 is 9 × 5 = 45.
Comparing the numerators, we have −40<−36 .
How is -28/84 expressed as a rational number with numerator 4?
Dividing both the numbers by 7.
A Which of the following sets of rational numbers is arranged in ascending order?
Convert the given fractions into equivalent fractions and then compare
-25/28 = -25/28
-5/14 = -10/28 (Multiplied both the numerator and denominator by 2)
-3/7 = -12/8 (Multiplied both the numerator and denominator by 4)
-1/2 = -14/28(Multiplied both the numerator and denominator by 14)
Therefore, option (c) is the correct answer.
Which of the following statements is false?
Hence, both (b) and (c) are false.
Which of the following is a rational number between 1/4 and 1/3 ?
Which of the following is the correct arrangement of in descending order?
LCM of 5,10,15 and 20 which is 60. Now making the denominator same, we have . So descending order is that is
LCM of 5,3 and 15 is 15
What is the sum of the additive inverse and multiplicative inverse of 2?
Additive inverse of 2 is −2
Multiplicative inverse of 2 is 1/2
∴ The sum of multiplicative inverse and additive inverse =
Subtract 2/3 from 7/8
Which among the following is a rational number equivalent to -5/-3 ?
Hence the correct answer is 5/3.
what is the Positive value of x?
Which number is in the middle if -1/6, 4/9, 6/-7, 2/5 and -3/4 arranged in descending order?
The descending order is
∴ The middle number is -1/6
What is the average of the two middle rational numbers when and are arranged in ascending order?
Arranging the given rational numbers in ascending order, we get
The two middle rational numbers
Their average is
Subtract -5/9 from -3/7.
What number should be added to -4/7 to get 5/9 ?
The correct answer is b
Let the number be x
What should be subtracted from -7/11 to get −2?
Let x be subtracted from -7/11
then -7/11 - x= -2
-x= -2 + (7/11)
-x= -2 + 7/11
By what rational number should -3/5 be multiplied to obtain 21?
The sum of two rational numbers is −3. If one of them is -11/5, find the other.
The correct answer is a.
Let the other number be x
Which of the following is the resultant of
