3 students share a bag of garri on such a way that the first student took 1/4 of the garri and the second 3/4 of the remainder. What fraction of the bag of garri did the third student take?

Answer 1

Let's assume the bag of garri is represented by 1 whole unit.

The first student took 1/4 of the garri, leaving 3/4 of the garri for the second student.

The second student then took 3/4 of the remaining 3/4, which is:
3/4 * 3/4 = 9/16

Therefore, the third student took 1 - (1/4 + 9/16) = 1 - (4/16 + 9/16) = 1 - 13/16 = 3/16 of the bag of garri.

So, the third student took 3/16 of the bag of garri.
