It is a composite number because it has more than two factors
235 is a composite number because it has more than two divisors - contrary to a prime which has exactly two divisors: 1 and the prime itself. 235 has 4 divisors: 1, 5, 47 and 235. A quick way to determine this is done by looking at the last digit. If it is either 0 or 5 the number is divisible by 5, thus it is not a prime.
They are all composite and rational numbers
235*98 = 235*(100 - 2) = 235*100 - 235*2 = 23500 - 470 = 23030 235*98 = 235*(100 - 2) = 235*100 - 235*2 = 23500 - 470 = 23030 235*98 = 235*(100 - 2) = 235*100 - 235*2 = 23500 - 470 = 23030 235*98 = 235*(100 - 2) = 235*100 - 235*2 = 23500 - 470 = 23030
