Question

Which elements in the set below are integers? 12, –3⁄4,√ 25 , –7, √ 5 , 14⁄7, 9 A. 12, √ 25 , –7, 9 B. 12, √ 25 , –7, 14⁄7, 9 C. –3⁄4, 25 , √ 5 ,14⁄7 D. 12, –7, 9

Answer 1

B. 12, √ 25 , –7, 14⁄7, 9.

Explanation:

14/7 = 2 and √25 = 5 so these are both integers.

Answer 2

Right option is : B. 12, √ 25 , –7, 14⁄7, 9

Explanation:

We have given,

Set of elements : 12, –3⁄4,√ 25 , –7, √ 5 , 14⁄7, 9

An integer number is whole number with positive and negative values but no fractional numbers.

From the given set of numbers:

12 , √ 25 = 5 ,
`(14)/(7)`=2 , -7 and 9 are integers.

`(-3)/(4)` and √5 are non integers.

Hence, right option is : B. 12, √ 25 , –7, 14⁄7, 9
