1/5 of students chose swimming 3/8 of the students chose tennis all the rest students chose cricket what fraction of students chose cricket

To make it easier, I’m going to make the fractions so that they both have the same denominator. To do this i have to multiply both the top and the bottom of one fraction by the other fractions denominator for both fractions.
When i do that, I get:

swimming: 8/40
tennis: 15/40

If you add those fractions together, you will get 23/40.

40-23=17 So, 17/40 of students chose cricket.

17/40

because 1/5 is will be 8/40

and 3/8 will be 15/40

plus those together will get you 23/40

40-23 is 17/40
