Question

what all whole numbers are there between 72 and 97?

how many whole numbers are there up to 50 ?

slove the following using a number line
1) 6+7
2)15-7
3)4×5
4)12÷6
​

Answer 1

Answer:

24 whole numbers are there in between 72-97

There are 51 whole numbers

Answer 2

The correct answers are given below:

• The number of whole numbers between two numbers a and b (excluding it), where b>a = b-a-1.

        We have been asked to find out what all the  whole numbers are

        there between 72 and 97. The number of whole numbers between

        72 and 97 is calculated as 97-72-1 = 24.

        The whole numbers between 72 and 97 are: 73, 74, 75, 76, 77, 78,

        79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92 93, 94, 95, and

        96.

• Whole numbers are calculated from 0. Up to 50, i.e. including 50, there are 51 whole numbers.

1. We are asked to find 6+7. Since 7 has a positive sign, we will have to move 7 positions to the right of 6 on the number line. We will end up at the number 13. Hence, 6+7 = 13.
2. We are asked to find 15-7. Since 7 has a negative sign, we will have to move 7 positions to the left of 15 on the number line. We will end up at the number 8. Hence, 15-7 = 8.
3. We are asked to find 4x5. This means that on a number line, we need to jump four places towards the right of 4 five times. We will end up at the number 20. Hence, 4x5 = 20.
4. We are asked to find 12÷6. This means that on a number line, we need to consider the line from 0 to 12 and try to divide it into equal parts such that each part contains 6 divisions. The number of such parts possible is 2. This is the answer to the given operation. Hence, 12÷6 = 2.
