Answer:
30%
Step-by-step explanation:
To find a percent, use this equation:
x/100 = n/t
where x is the percent, n is the select number of things, and t is the total number of things
Substitute:
x/100 = n/t
x/100 = number of shots Marin made/number of shots attempted
x/100 = 12/40
Now, we need to cross multiply, or multiply the numerators by the denominators of the other fraction, and vice versa.
Multiply:
x/100 = 12/40
x(40) = 40x
100(12) = 1200
40x = 1200
Now, divide both sides of the equation to find the value of x.
Divide:
40x = 1200
/40 /40
x = 30
Now we have the percent is fraction form: 30/100
To make it a percentage, simply take the numerator and add the % sign.
Therefore, Martin made 30% of his shots.
