Question

How many whole numbers are there between 32 and 53?

Answer 1

Hint:
Here, we will subtract the two numbers and hence, subtract 1 from the difference to find the required number of whole numbers lying ‘between’ 32 and 53. Whole numbers are those numbers which include all the positive numbers: $1, 2, 3, 4,....$ and zero.

Complete step by step solution:
Now, in order to find the number of whole numbers between two given numbers, we should follow the following steps:
1) First of all, we will subtract the smaller number from the larger one.
2) Then the difference obtained also includes one of the two numbers, hence, we will subtract 1 from the difference because we are required to find the numbers between the two given whole numbers, hence, the two given numbers must be excluded.
3) After subtracting 1, we will get the required numbers which lie between the given two whole numbers.
Hence, now, we will follow these steps and find the total number of whole numbers lying between 32 and 53.
1) First of all, we will subtract 32 from 53 as it is smaller than 53.
2) Hence, we get, $\left( {53 - 32} \right) = 21$
3) But, this includes one of the given two numbers, hence, after subtracting 1, we get,
$\left( {21 - 1} \right) = 20$
Therefore, there are 20 whole numbers between 32 and 53.

Thus, 20 is the required answer.

Note:
Since, the given two numbers are not that far from each other. Hence, we can even write the numbers lying between them and then, count them together to find the required total number of whole numbers lying between them.
Thus, the whole numbers lying between 32 and 53 are:
33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52
Now, if we count these numbers, then we get the required answer as 20.
But, this method is only possible if the difference between the two given numbers is less.
Hence, 20 is the required answer.
