The composite numbers are: 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86 ,87, 88
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.
81, 82, 84, 85, 86, 87, 88. 80 and 90 are composite too

Composite numbers have factors other than 1 and itself. So, two good examples are: 62 and 84
The numbers in the 90s are all composite, apart from 97, which is prime.

85, 86 and 87
Yes, the numbers from 90 to 96 are composite numbers.
Composite numbers between 89 and 97 are 90, 92, 93, 94, 95, 96.
63, 64
The composite numbers between 83 and 90 are 84, 85, 86, 87, 88, and 90. A composite number is defined as a positive integer that has at least one positive divisor other than one and itself. In this range, all these numbers have factors other than one and themselves, making them composite.
60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90 are the composite numbers in that range.
81, 82, 84, 85, 86, 87, 88. 80 and 90 are composite too

All of them except for 83 and 89 which are prime numbers
