Which of the following rational numbers is negative?
(a) -(-3/7)
(b) -5/-8
(c) 9/8
(d) 3/-7
Solution:
We have to find the rational number which is negative
From the options,
-(-3/7) = 3/7
So, -(3/-7) is positive
-5/-8 = 5(-1)/8(-1) = 5/8
So, -5/-8 is positive
9/8 is positive
3/-7 = 3(1)/7(-1)
Therefore, the rational number which is negative is 3/-7.
✦ Try This: Which of the following rational numbers is positive? (a) -8/-7, (b) -(9/-11), (c) 3/-4, (d) 21/13
From the options,
-8/-7 = 8(-1)78(-1) = 8/7
So, -8/-7 is positive
-(9/-11) = -9/-11 = 9(-1)/11(-1) = 9/11
So, -(9/-11) is positive
3/-4 = 3(1)/4(-1)
So, 3/-4 is negative
21/13 is positive
Therefore, the rational number which is negative is 3/-4
