Answer:
45
Step-by-step 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.
√(1/121) = √1 / √121 = 1 / 11 = <em>11⁻¹</em>
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
Factors of 45: 1, 3, 5, 9, 15, 45
The common factors between the two numbers are 1, 3, 5, 15.
Hope this helps!
