Answer:
One!
Explanation:
Split a circle into 3 equal parts. Take one. That one part is 1/3 of the circle!
Fractions are essentially division, but when you multiply an integer (whole number) by a fraction, only multiply the number by the numerator (top number). 1x3/3 = 3/3, and 3 divided by 3 equals 1! Hope this helps!
