13/100*x=39;
13x=3900;
x=300;
so he shot 300 shots

First, let's understand what 13% means.
13% means, 13/100, means if Monique tries to score for 100 times consecutively, she'd succeed 13 times. (Of course, this is over a long period of time, and sometimes she'd do better, sometimes worse. But on average, she should get 13 out of every 100 shots).

So this time, she scored 39 goals.
That's a lot more than 13. How many more? Well, to put it precisely, she scored 26 more. But knowing 26 doesn't help to tell us how many shots she tried in total.

If we know she'd get 13 for every 100 shots, then we need to find out how many 100 shots she tried to get 39 goals.

So, we divide 39/13 = 3
*Why divide? Because division tells you how many "portions" you have rather than how many individual objects you have.

So now we know where are 3 portions of 13s to make 39.
Then we know Monique must have tried 3 times as harder to make 39 goals rather than 13.

So, each time is 100 shots, 3 times as harder = 300.

Answer: Monique made 300 shots.

(13/100)x=39 where x=no of shots
x=300

(13/100)n = 39
n = 39/(13/100)
n = (39/1)/(13/100)
n = (39/1)*(100/13)
n = (3900/13)
n = 300

ANS : 300 shots

.13x = 39
x = 39/.13
x = 300
