1 / 3 * 1/4 * n = 15.
1/12 *n = 15,
n= 12 *15 = 180,
3/10 * 180 = 54.
1/12 *n = 15,
n= 12 *15 = 180,
3/10 * 180 = 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.

1/3*1/4=15,
1/12=15,
12*15=180,
then take3/10=180,
3/10*180 = 54.
1/12=15,
12*15=180,
then take3/10=180,

@Vishwak.
In Question: three-tenth becomes 3/10 of that number is 180.
So, 3/10*180 = 54.
