There are 37 odd numbers between 1 and 75. This can be calculated by dividing the total range (75) by 2, which gives us 37.5. Since we cannot have half of an odd number, we round down to the nearest whole number, which is 37. Therefore, there are 37 odd numbers between 1 and 75.
Oh, what a delightful question! Let's take a moment to appreciate the beauty of odd numbers. Between 1 and 75, there are 38 odd numbers. Each one is unique, just like a happy little tree in a vast forest. Keep counting and exploring, my friend.
Oh, dude, let me break it down for you. So, between 1 and 75, there are like 37 odd numbers. You see, odd numbers are those that aren't divisible by 2, so you just gotta count 'em up. Easy peasy lemon squeezy!
36 odd numbers: 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73.
The odd numbers between 60 and 75 are: 61, 63, 65, 67, 69, 71, 73
75 - 1 = 74 numbers between 1 and 75. Divide 74 by 2 = 37 even numbers.
There are 24 numbers between 75 and 100. To find this, you subtract the lower limit (75) from the upper limit (100) and then subtract 1 because you don't want to count the limits themselves. So, 100 - 75 - 1 = 24 numbers between 75 and 100.
The odd numbers between 70 and 90 are 71, 73, 75, 77, 79, 81, 83, 85, 87, and 89. We know right away that 75 and 85 are composite, since they're divisible by 5. 81 is composite since it is the square of 9. 77 is obviously divisible by 11, so it, too, is composite. 87 is divisible by 3 since 8 + 7 = 15, which is divisible by 3. Therefore, and trust me, I double-checked the rest, 75, 77, 81, 85, and 87 are the composite, odd numbers between 70 and 90.
All of the whole numbers between 50 and 75 are composite numbers, except 53, 59, 61, 67, 71, and 73.
