A marksman is shooting at a target hits it 12 1/2% of the time. How many times must he shoot to register 100 hits.??
Answered by Ms. Sue
I showed you how to do this kind of problem. Now it's your turn.

How do you think this problem can be solved?

Answered by sia
hmmm okay 12x 1/2=100
12x=100
x=8.33?
Answered by Ms. Sue
Your answer doesn't make any sense. The marksman must have to shoot many times 100 to register 100 hits.

Try again.
Answered by sia
12.5x=100/12.5
x=8?
Answered by sia
do you multiply the 12.5 by 100?
Answered by sia
x * 12.5% = 100
x * (12.5/100) = 100
.125x = 100
x = 100/.125
x = 800
Answered by Ms. Sue
You need to change the percent to its decimal equivalent.



Answered by sia
So just do 0.125/100
Answered by Ms. Sue
0.125x = 100

x = 100/0.125
