Select the list which contains ten examples of rational numb

Select the list which contains ten examples of rational numbers. Which of the three lists contains only rational numbers? Squareroot 7, 28, Squareroot 3, pi/2, 7 1/2, pi/3, -2.75, 7, - 5/7, 6.12 -5, 10.6, 654, 5/17, 0.9, 7/3, 1 3/7, -8, Squareroot 2, 0.4 6.12, -4.7, 36, 1/2, 0.333 ..., - 23/8, 19, 1 2/3, 7/5, 0.777

Solution

A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers.

Option A has sqrt3 , sqrt7 which are non rational numbers

Option B has all rational numbers except sqrt 2 can also be whoch is irrational numbers

Option has 0.33.... , 0.777 which are irrational numbers

So, Option B has only one irrationla number remaining all are rational numbers

None of them contain 10 rational numbers
