there are 39 whole numbers between 21 and 61
There are no whole numbers between 20 and 21. Only fractions or decimals exist between these two numbers. Whole numbers between 20 and 25 are 21, 22, 23, and 24.
Infinitely many. In general, between ANY two DIFFERENT numbers, there are infinitely many other numbers.
Whole numbers are known as zero plus the "counting numbers." (1, 2, 3, ...) So, the whole numbers of 21 would be 0 - 21. (23 numbers.)
Four. The prime numbers between 10 and 21 are 11, 13, 17, and 19.
11 numbers:6, 9, 15, 21, 33, 39, 51, 57, 69, 87 and 93.
There are no whole numbers between 20 and 21. Only fractions or decimals exist between these two numbers. Whole numbers between 20 and 25 are 21, 22, 23, and 24.
Between 52 and 73 there are 53, 54, ..., 72 a total of 72 - 53 + 1 = 20 numbers. Including 52 and 73 there are 22 numbers.
Infinitely many. In general, between ANY two DIFFERENT numbers, there are infinitely many other numbers.
Three numbers between 21 seconds and 22 seconds are 21.1 sec, 21.2 sec, and 21.3 sec
-21
The two consecutive whole numbers that 20 lies between are 19 and 21. This can be determined by recognizing that 20 is the average of 19 and 21. In other words, (19 + 21) / 2 = 20. This demonstrates that 20 is exactly halfway between 19 and 21 in the number line.
4 and 3 * * * * * 19 is itself a whole number and no whole number can lie between two consecutive whole numbers.
Whole numbers are known as zero plus the "counting numbers." (1, 2, 3, ...) So, the whole numbers of 21 would be 0 - 21. (23 numbers.)
21/4 is not a whole number and it cannot be represented as consecutive whole numbers.
Four. The prime numbers between 10 and 21 are 11, 13, 17, and 19.
There are 21.
11 numbers:6, 9, 15, 21, 33, 39, 51, 57, 69, 87 and 93.
