Write and solve a proportion to answer the question. 36 is 0.9% of what number

_ = 0.9/100

w = _

(i forgot how to do this stuff haha)

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
