The denominator of a fraction is 4 more than the numerator. If both the numerator and the denominator are decreased by 2​, the resulting fraction is equivalent to 9/13. Find the fraction.

i think its 11/15 because if both the denominator and numerator decrease by 2 then you just add 2 to the answer

I'm not sure if this is correct

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
