There are 8 composite numbers between 90 and 100. They are 91, 92, 93, 94, 95, 96, 98, and 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 greater than 88 and less than 95 are: 90, 91, 92, 93, 94.(88 and 95 are themselves also composite.)
The answer depends on your skills and your knowledge of relationships between numbers. 76/95 might look hard but it is not if you recall (from your 19 times table) that 76/95 = (19*4)/(19*5) = 4/5 = 0.8.
Composite numbers between 89 and 97 are 90, 92, 93, 94, 95, 96.
