Thread: 8(2/7)% doesn't equal 58/7 ??

I am taking a Pre-College Mathematics (Math 050) Midterm 1 Review test. The question in question is:

Write 8(2/7)% as a fraction.

My answer was 58/7, which was an option, "B". However, the answer key gives the answer as "A", which is 29/350.

First, I got it in my mind that I should multiply the whole number by the denominator and then add that product to the numerator, keeping it over the denominator: ((8*7)+2)/7, which is 58/7. Is this incorrect? If so, where did I learn that process?

Second, I went wrong in not expressing the percentage as a fraction. How do I do that?

the percent-sign means that you have to multiply your frction by . Therefore:

Why does 8(2/7) = 58/7

I thought 8(2/7) was 8 x 2/7 = 16/7

I suspect the notation attempts reference to the number 8 and 2/7, that is .
