12 / 4 = 3. That means that 3 lots of 4 go into 12. If the 2 fractions are equivalent, then the numerator (the top number) for 3/4 times by 3 should equal the numerator for 11/12. However, 3 X 3 = 9. 9/12 is not the same as 11/12.
It's 20. You start with the parentheses and 8 + 12 is 20. Then you have the brackets next, and so that's 20/4 and that's 5. Then all you have left is 4 x 5 which is 20.

Lcm of 60 and n = 420
Stated: n <90 and a multiple of 6
420/60 = 7 thus n must be a multiple of 7
Therefore n =42 or 84
