A rational number is any number that can be written in a/b form (like a fraction). So it just can't be a repeating decimal like how pie goes on forever. So let's see. 8.05 could work. Since you could write that as 8.05 over 1 (8.05/1)
20% + 20% + 25% + 35% = 100% = 800
800 ÷ 100 = 8
8 × 25 = 200 has chosen baseball
and
8 × 20 = 160 students chose basketball
so the answer is 40
