30% just means 30/100 which can be simplified to 3/10. In order to find the number of hits you just need to multiple .3 by the total attempts, being 240, which comes out as 76.
762 rounded to the nearest hundred is 800 hundred
remember this rule: five or above give it a shove four or less give it a rest
I believe that would equal 65/21
hope that helps!
