This sounds like a homework question. If it is I'll help you but I'm not going to give you the answer.
Do you know proportions?
If so:
1. Put 5 over 31 for march and set that equal to x over 100. The x stands for the percentage.
2. Cross multiply and your results would be 31x=500.
3. Then divide the 31 and then then the whole number that you get in the end will be the percentage.
4. You do the same for April (30 days) and May (31 days)
5. If you need the percentage for all days added together for all three months, then it would be 16 over 92 = x over 100.
6. You'll repeat steps 1, 2, & 3

March = 16.129%
April = 26.667%
May = 9.677%
The month with the highest percentage of rainy days is April.

The first thing you need to do is to calculate what percentage of the month a single day represents.
If there were just two days then each day would be 50% of the month (100 ÷ 2) but March and May both have 31 days and April has 30 days.
100 ÷ 31 = 3.226%, so one day in March or May = 3.226% of the entire month. For April you need to divide 100 by 30 which = 3.333%.
There were 5 rainy days in March, 1 day = 3.226% so 5 days = 16.129% (5 x 3.226).
There were 8 rainy days in April, 1 day = 3.333% so 8 days = 26.667% (8 x 3.333).
There were 3 rainy days in May, 1 day = 3.226% so 3 days = 9.677% (3 x 3.226).

The % of rainy days in any month is
#rainy days in the month/ no. of days in the month.
So for example, March had 5 rainy days and has 31 days in it so the % of rainy days is 5/31 =.161
For April 8/30 = .267
I let you do May which has 31 days.

Easy peasy.
March had 5/31 days of rain.
April had 8/30 days of rain.
May had 3/31 days of rain.
To convert this to percentage you need to convert 31 (total days in March) to 100 (total %)
5/31 = x/100
5 * 100 = 31 * x
x = 500/31 = 16.13 (aproximately)
Same drill with the others...
8/30 = x/100
You get the idea.

March had 5 of 31 days rain = 5/31 = .1613 = 16.1%
April had 8 of 30 days rain = 8/30 = .2667 = 26.7%
May had 3 of 31 days rain = 3/31 = .0967 = 9.7%
Therefore, April had the highest percentage of rainy days. :)

It sounds like you're just trying to get someone to do your math homework for you. Homework is not a quest. It's a responsibility and you should do it yourself. You don't learn anything by having other people give you the answers.
