1/6
Explanation:
He ate 1/2 of 1/3 of the cake, so the fraction of the whole cake he ate is 1/2 x 1/3. Multiplying fractions is easy, simply multiply the numerator of each fraction (the numbers at the top of each fraction) and the denominator of each fraction (the numbers at the. bottom of each fraction). Therefore, 1/2 x 1/3 = 1/6.
