Okay, so, you'd have to first multiply 2/3 and 2/5, which gives you 4/15.
This means that, overall, 4/15 students study French, which means that 11/15 students do not study French.

15 and 27
Step-by-step explanation:
let the smaller number be n then the larger number is n + 12 and
n + n + 12 = 42, that is
2n + 12 = 42 ( subtract 12 from both sides )
2n = 30 ( divide both sides by 2 )
n = 15
and n + 12 = 15 + 12 = 27
The 2 numbers are 15 and 27
