Question

Andrew, James and Jenny share a box of chocolates

Andrew eats 1/3 of the chocolates, James eats 2/5 and Jenny eats 1/10.
What fraction of the box is left?

Answer 1

The fraction left is 1/6

Explanation:

To get the fraction of the box that is left, first let us add all the fraction shared together:

1/3 + 2/5 + 1/10

To add the above fractions, find the lcm of 3, 5 and 10. The lcm is 30.

Next, divide the lcm(i.e 30) by the denominator of each fraction and multiply the result with their respective numerator to obtain the following:

1/3 + 2/5 + 1/10 = (10+12+3)/30 = 25/30 = 5/6

Now we assume that the total of what was shared is 1. To get the fraction left, we do the following:

1 — 5/6 = (6 —5)6 = 1/6

Therefore, the fraction left is 1/6
