Answer:
Charles missed 2 shots
Explanation:
Alrighty, so Charles shot 40 times and of those 40 times, he missed 10 times. We can represent that as a fraction:
10/40
It also says that if he were to shoot 8 times, how many baskets would he miss. In the fraction above we have:
shots missed/total shots
Proportions can help us solve this:
10/40 = x/8 (we have an x because we don't know how many baskets he missed; that's what we're trying to find)
Now we can cross multiply and arrive at our answer, x:
40x = 80
x = 2
This means that Charles must've missed 2 shots.
Hope this helps :)
