Which of the following does not represent an integer
a. 0 ÷ (-7)
b. 20 ÷ (-4)
c. (-9) ÷ 3
d. (-12) ÷ 5

Solution:

To determine which of the above listed options does not represent an integer we will solve the given expressions of individual options using integer properties.

a) 0 ÷ (-7) = 0

b) 20 ÷ (-4) = -5

c) (-9) ÷ 3 = -3

d) (-12) ÷ 5 = -2.4

Therefore, on simplifying individual options we observe that the option (d) (-12) ÷ 5 = -2.4 does not represent an integer value it gives a decimal value.

✦ Try This: Simplify (-82) ÷ 9. Does it represent an integer value?

Using the integer rules, division rules and the BODMAS rules we can determine the value of (-82) ÷ 9. Thus can examine whether it represents an integer value or not
