because 2/3 times by 2/5 is 4/15, so this means 4/15 students do study french, this would means that 11/15 do not study french because you do 15-4=11.

You are literally almost there, you’ve done the hard bit. Now, 4 out of 15 people study french, so the rest of the 15 people don’t, in other words 11 out of 15 don’t (15-4=11) so you’re ratio would be....

Everybody else does not study French (because they either study another language or they don't study any foreign language).

Its the ratio of
French speakers : not french speakers

So for every 4 french speakers, how many do not speak french? Thats the ratio.

11:15 would be the ratio of not french : everyone
You want the ratio of french : everyone except french, so the correct answer is 4:11
