Answer 1

45

Explanation:

If you treat this as a ratio, it would be 3 vowels to every 7 tiles. If one value in the ratio is multiplied by a number, the other should be multiplied by the same number. So if there are 105 tiles, the 7 in the ratio was multiplied by 15. Multiply the other value, 3, by the same number and you get 45.
