Look up a list of prime numbers (a Google search for "prime numbers" or "list of prime numbers" should do); every number (greater than 1) that is NOT a Prime number is composite.
There are 8 composite numbers between 90 and 100. They are 91, 92, 93, 94, 95, 96, 98, and 99.
Let's try 99 and 98! 99 is 3 x 3 x 11 and 98 is 2 x 7 x 7 98 and 99 are consecutive numbers, composite numbers, less than 100 and there is no prime numbers between them!
99 is the largest composite number before 100.
There are 900 three-digit numbers, all of which are between 99 and 3,000.
88
There are 8 composite numbers between 90 and 100. They are 91, 92, 93, 94, 95, 96, 98, and 99.
Let's try 99 and 98! 99 is 3 x 3 x 11 and 98 is 2 x 7 x 7 98 and 99 are consecutive numbers, composite numbers, less than 100 and there is no prime numbers between them!
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
There are 49 even numbers between 1 and 99.
99, 100, 102, 104, 105, 106, 108, 110, 111, 112, 114 (including 99 and 114)
composite numbers are numbers that can be divided by something other than one. in other words, non-prime numbers. thus, these numbers are composite numbers: 86, 96, 85, 87, 99, 100, 82, 84 and these are not composite numbers: 67, 73
99 is the largest composite number before 100.
99
There are 99 numbers between 0 and 100.
There are 10 composite numbers from 90 to 100 (including the boundaries):90, 91, 92, 93, 94, 95, 96, 98, 99 and 100
98 if you exclude 0 and 99.
There are 900 three-digit numbers, all of which are between 99 and 3,000.
