Question

When 18 is divided by _____, it gives zero as the remainder.

• A. 7
• B. 4
• C. 5
• D. 3

Answer 1

The correct option is D 3

Anything left after equal division is known as the remainder.
And when nothing is left after division, it gives zero remainder.
Here,
(a) When 18 is divided by 7:
18 − 7 = 11
11 − 7 = 4
Since no further division is possible,
therefore, when 18 is divided by 7, the remainder is 4.

(b) When 18 is divided by 4:
18 − 4 = 14
14 − 4 = 10
10 − 4 = 6
6 − 4 = 2
Since no further division is possible,
therefore, when 18 is divided by 4, the remainder is 2.

(c) When 18 is divided by 5:
18 − 5 = 13
13 − 5 = 8
8 − 5 = 3
Since no further division is possible,
therefore, when 18 is divided by 5, the remainder is 3.

(d) When 18 is divided by 3:
18 − 3 = 15
15 − 3 = 12
12 − 3 = 9
9 − 3 = 6
6 − 3 = 3
3 − 3 = 0

Since no further division is possible,
therefore, when 18 is divided by 3, the remainder is 0.
