To answer this question you will utilize your reading skills and knowledge of how to compute with percents. You need to read carefully and see that we need to find out what 25% of last months number of bugs is. Using math we will convert 25% into an number we can calculate with (either a decimal or a fractions). I like fractions in this case because 1/4 can be easily multiplied by 8. You may also multiple 0.25 times 8 if you prefer decimal calculations. Either way, the answer is 2. This is how many more bugs the spider ate, so to find the total for this month we add 8 and 2 to get 10 bugs.
