I do not understand this problem
CommentI think you need brackets to clarify what you mean. I think it should be written as
10b/(2b + 8)
If that is the case the reciprocal is
(2b + 8)/10b You just turn everything up side down. There are technical ways of doing this, but the easiest way is just to do what I just did.
Put the numerator in the denominator,
Put the denominator in the numerator.
You could simplify this a bit.
2b/10b + 8/10b
which reduces further.
1/5 + 4/5b
Just to make sure you understand where that b is, I will do this in
Latex.
Alternate answerIf you do mean what your wrote then the reciprocal is 2b / 10b + 8 which is 1/5 + 8 = 8 + 0.2 = 8.2
The 8 has nothing to do with the reciprocal under these conditions.
The answerI have given you all the choices I can think of without going into decimals. If you have choices, please list them under the comments.
Answer:
2.375 has the same value as 2 and 3/8.
Percent formula : is/of = %/100
is = 10.03
of = 29.5
percent = x
now we sub
10.03/29.5 = x/100
this is a proportion, so we must cross multiply
(29.5)(x) = (10.03)(100)
29.5x = 1003
x = 1003/29.5
x = 34 <==== 10.03 is 34% of 29.5
