21 over 66 is 21/66, and to simplify you must find to common factors of the two numbers ( the denominator and the numerator). a common one in this case is 3. 66 divided by 3= 22 and 21 divided by 3=7So the answer is 7/22 (7 over 22)

Almost. 21/7 = 3, but 22/7 = 3 & 1/7.
20. 22+21+19+19+19 = 100. 100 divided by the amount of numbers, which is 5, equals 20.
no because 21 can be divided by 3, 7, and itself now 22 is not a prime factor either because it can be divided by 2 and 11 and of course itself, And prime factor is a number that can only divided by 1 and itself

20. 22+21+19+19+19 = 100. 100 divided by the amount of numbers, which is 5, equals 20.
42 can be divided by 2 once. The result, 21, is not divisible by 2.
mean = the sum of 23, 19, 26, 17, 21, 24, 22 divided by 7 = 152/7 =21.71

You can work this out, Prime numbers can only be divided by themselves or 1. Therefore as 20 can be divided by 2 it it not prime. The same is true for 22 and 24. Thus the prime must be either 21 or 23. See if either of these numbers can be divided by 7, if it can then the prime must be the other number.

22 is divisible by 1,2,11,22 because 22 divided by 1 can be done. 22 divided by 2 can be done. 22 divided by 11 can be done and lastly, 22 divided by 22 can definitely be done.
