How many positive 2 digit numbers are not divisible by 6

10, 14, 16, 20, 22, 26, 28, 32, 34, 38, 40, 44, 46, 50, 52, 56, 58, 62, 64, 68, 70, 74, 76, 80, 82, 84, 86, 90, 92, 96, 98

Step-by-step explanation:

Basically you find 6, your least common denominator. Plug that into the next highest value, (starting at 10 would be 12), and those are the numbers you won't be able to use. If you want a faster way of doing this, take every even number 10-99 and put it in a calculator, divide by 6. If it is a decimal then those will be in your awnser, if its a whole number, that will not be your awnser. Hope this isn't too confusing and good luck!
