Finding fractions of numbers

This is how you do fractions of numbers. These are the numbers: 1/3 of 27, 1/6 of 36 and 1/10 of 50. To work it out you need to divide the numbers like this: divide 27 by 3. That is 9 so the fraction is 9. If it was 2/3 instead of 1/3 the answer would be 18 because it doubles.
