Composite numbers have factors other than 1 and itself. So, two good examples are: 62 and 84

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.

Yes, the numbers from 90 to 96 are composite numbers.

Composite numbers between 89 and 97 are 90, 92, 93, 94, 95, 96.

81, 82, 84, 85, 86, 87, 88. 80 and 90 are composite too

14Composite numbers between 70-90:72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88

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

All the prime numbers between 60 and 90 are: 61 67 71 73 79 83 and 89

There are 8 composite numbers between 90 and 100. They are 91, 92, 93, 94, 95, 96, 98, and 99.

90 is composite. (Tip: all whole numbers ending in zero are composite).

number of composite numbers between 81 and 100 = 15composite numbers between 81 and 100 = 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99

The numbers between 89 and 97 are: 90, 91, 92, 93, 94, 95, 96. All even numbers greater than 2 are composite. All numbers greater than 5 are divisible by 5 are composite. 93 is divisible by 3, so that only leaves 91 as a prime number. The composite numbers are 90, 92, 93, 94, 95, 96.

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

The numbers 90, 91, 92, 93, 94, 95, 96, 98, 99 and 100 are composite (including the boundaries).

60 and 90 are the numbers between 50 and 100 that are factors of 180

There are 10 composite numbers from 90 to 100 (including the boundaries):90, 91, 92, 93, 94, 95, 96, 98, 99 and 100

These steps can reduce our work: First of all we will write all the even numbers between 89 and 97: 90, 92, 94 &amp; 96. Then multiples of 5: 90 &amp; 95. Multiples of 3: 90, 93 &amp; 96 and also the multiple of 7 which is 91. There is no other number left between 89 &amp; 97. Therefore, numbers between 89 &amp; 97 are all composite numbers.

The numbers in the 90s are all composite, apart from 97, which is prime.
