40% of the kids at the picnic went swimming if there were 25 kids, how many went swimming

Hey there!

To find how many kids went swimming given that there were 25 kids in total and 40% of them went swimming, you must multiply the percent by the whole:
40%*25

Before you do this, first convert the percent to a decimal:
40%=0.40

Now, multiply your expression:
0.40*25
0.40*25=10

Therefore, your final answer would be that 10 out of the total 25 kids went swimming.

Hope this helps and have a nice day! :)
