Step-by-step explanation:
given, 1/5 of a number is subtracted from 1/3 of that number, the result is 6.
x/3 - x/5 = 6
=> 5x - 3x/15 = 6
=> 2x = 90
=> x = 45.
Thus the number is 45.

Okay, so let's assume the number to be 'x'.
According to the question,
1/3x - 1/5x = 6
--> x [1/3 - 1/5] = 6
--> x [2/15] = 6 ------ (LCM)
--> x = 6 [15/2] ------ (Reciprocal)
--> x = 15 × 3
--> x = 45
∴ The required number = 45
