For a non-zero integer a which of the following is not defined
a. a ÷ 0
b. 0 ÷ a
c. a ÷ 1
d. 1 ÷ a

Solution:

To determine the correct option let us analyze the individual options by substituting an integer value.

a) a ÷ 0 = a/0 is not defined

b) 0 ÷ a = 0

c) a ÷ 1 = a/1

d) 1 ÷ a = 1/a

Therefore, for a non-zero integer a option (a) a ÷ 0 = a/0 is not defined

✦ Try This:  If a = 27 determine the value of a × 2 - a +2a.

By substituting the value of a and further using the integer rules and the BODMAS rules we can determine the value of a × 2 - a + 2a
