Question

Which of the rational number -11/28,-5/7,9/-14,29/-42 is the greatest

Answer 1

Given: The rational numbers = -11/28, -5/7, 9/-14, 29/-42

To find: Which among the above is the greatest?

Solution:

• As we have given the rational numbers = -11/28, -5/7, 9/-14, 29/-42, we can notice that all the denominators of the given rational numbers are different.

• We can also identify that the denominator of all given rational number is multiple of 7.

• So first we need to make all the denominators same, we get:

                 -11/28 x 1.5/1.5 = -16.5 / 42

                 -5/7 x 6/6 = -30/42

                 9/-14 x 3/3 = -27/42

                 29/-42

• Here we have made denominators equal to 42.

• Now lets write again and compare:

                -16.5 / 42 , -30/42 , -27/42 , -29/42

• Largest = -16.5 / 42

Answer:

        So among all these fractions, - 16.5 / 42 is the largest one.

Answer 2

the answer of this question is 29/-42
