The unknown part of the circle is 1/6.
In the question, we are given that the provided circle represents a whole, or 1. We are asked to determine the unknown part of the circle using subtraction.
Fractions of the circle given to us are 5/12, 1/12, and 1/3.
Thus, the total part of the circle, that has been given to us is 5/12 + 1/12 + 1/3
= (5 + 1 + 4)/12
= 10/12
= 5/6.
The remaining part of the circle can be calculated by subtracting the given part of the circle from the whole, that is,
the remaining part of the circle = Whole - Given part of the circle,
or, the remaining part of the circle = 1 - 5/6,
= (6 - 5)/6
= 1/6.
Thus, the unknown part of the circle is 1/6.
