same question here, with slightly different wording

If you make 10 out of 16 shots in basket ball , how many shots do you have to miss to lower your record to 40%???
Is this kind of right
10/16 × 40/100 = 5/20 reduced to 4
Or am I totally wrong

Ok thanks so he has to miss four shots
Your calculation makes no sense, so yes, you are totally wrong.
In the wording of the question I linked to, it said "How many consecutive free throws must he miss" , yours does not say that.
The way yours is worded, there could be shots that he made and shots that he missed, so without further data, the answer cannot be found
If , like in the first question, you are dealing with consecutive misses, then
10/(16+x) = 40/100 = 2/5
32 + 2x = 50
2x = 18
x = 9
check: now he has 10 hits out of 16
so he misses the next 9 shots
he still has only 10 hits, but he took 25 shots
percentage of hits = 10/25 = .4 or 40%
