Important Questions Test: Whole Numbers - Class 6 MCQ

 0 does not have a predecessor.

The option (b) is the correct answer.

The smallest whole number is 0.

The option (c) is the correct answer.

We know that

1 million = 1,000,000

So the successor of 1 million = 1,000,000 + 1 = 1,000,001

The option (a) is the correct answer.

For Example-

Consider whole number = 1

So the successor of 1 = 1 + 1 = 2

Product between them = 1 × 2 = 2

Hence, 2 is an even number.

The option (d) is the correct answer.

For example-

Consider an even natural number = 2

So the predecessor of 2 = 2 − 1 = 1

We get the successor of 2 = 2 + 1 = 3

Product between them = 1 × 3 = 3

Hence, the product is an odd number.

 There is no predecessor for natural number 1. As natural number starts from 1

The option (b) is the correct answer.

We know that we get multiples by multiplying the number by any number.

Hence, every counting number has an infinite number of multiples

Answer: b) 15
Explanation: The first five whole numbers are 0, 1, 2, 3, and 4. Their sum is 0 + 1 + 2 + 3 + 4 = 15.

Concept:

Counting the whole numbers within the given range.

Solution:

⇒ The sequence of whole numbers between 0 and 10 is: 1, 2, 3, 4, 5, 6, 7, 8, 9

⇒ We simply need to count these numbers.

⇒ There is 1 one. ⇒ There is 1 two. ⇒ There is 1 three. ⇒ There is 1 four. ⇒ There is 1 five. ⇒ There is 1 six. ⇒ There is 1 seven. ⇒ There is 1 eight. ⇒ There is 1 nine.

by adding all the counts, we get 9 whole numbers between 0 and 10.

Hence, the correct answer is "9".

We know that the factors of

91 = 1 × 7 × 13

81 = 1 × 3 × 3 × 3 × 3

87 = 1 × 3 × 29

97 = 1 × 97

Hence, 81, 87 and 91 are not prime numbers.

There 29 numbers between 38 and 68 . Hence the number of whole numbers between 38 and 68 are 29
use m - n - 1 for finding no of terms
= 68 - 38 - 1 = 29

Successor=1000
Predecessor=998
Product= 1000×998
= 998000

Let the whole number be x
According to the question
= x + 25 + 25 - x
= 50

We know that the predecessor of an odd number is an even number and the successor of an odd number is also an even number.

So the two even numbers and their product are two consecutive even numbers which is always divisible by 8.
