What percent of 120 is 90

pls help me .i need to knoe pls

%75

Step-by-step explanation:

the equation you will use is: percent times the original number equals the part. because you know the original number, and you know the part, you need to find the percent. so, plugging what we know into the equation, we can use x for the unknown percent, we get x(120) = 90. then, we divide both sides by 120 because we want x by itself, and we get x = 0.75. because x represented percent, we have now found that 90 is 75% of 120.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
