The question said 1/3 of 1/4 of x is 15.
To get x we need to increase 15 by 4 times, we get 60, and then we need to increase 60 by 3 times to get x.

1/3 multiple by x/4 = 15.
X = 180.
3/10. Multiply by 180
gives 54.
X = 180.
3/10. Multiply by 180
gives 54.

(1/3*1/4) * x = 15.
X/12 = 15,
X = 15/12,
X = 180,
3/10 = 180,
= 3 * 18,
= 54.
X/12 = 15,
X = 15/12,
X = 180,
3/10 = 180,
= 3 * 18,
= 54.
