Answer:
20 percent
Step-by-step explanation:
(I had such a good explanation and accidentally refreshed the page)
So basics
48/60 is in
12/60 is out
Now we focus on out
we know this 12/60 becuase 48 is in and there are 60 tries so 60-48=12
So now 12/60 into a percent
A percent is basically x/100
So we gotta make 12/60 into a fraction with a denominator of 100
SO simplify fto make it easier (try to get it to 4,2,5,10,50,25 anything that goes into 100)
1/5
1/5 is 20 percent
thats a benchmark
But if you don’t know
You can always do a pro proton
1/5=x/100
Cross multiply
100=5x
x=20
