Question

Jane was assigned a project to number and colour desks based off certain criteria. If

the desk was brown, she would label it in multiples of 4 (where the first is 4, the
second is 12, etc.) and the colour would remain the same. If the desk was white, she
would number the desk in multiples of 5 (where the first is 5, the second is 10, etc.)
and colour those that she numbered with an even number green. If there were
originally 5 brown desks and 6 white desks, what fraction of the even numbered
desks will be coloured green?

Answer 1

5/3 or 3/5

Explanation:

If there were 5 brown desk, it will be:

4,12,36,108,304

If there were 6 white desk, it will be:

5,10,15,20,25,30

Putting them it fraction: brown/white:

5/3

If putting them in this fraction: white/brown:

3/5
