45 7/8 out of 100 meters... how do I solve this?

Answers

I think, based on the little info that you gave:), you would have to make 45 7/8 into a mixed number which would be 367/8. then you would have to make that all out of 100.
(367/8) / 100) = .45875.  Then you could move the decimal place over and you would get 45.875% which when rounded would be 46%.  You can do this on a calculator to check by finding the decimal value of 7/8 which is .875, then add 45 to it to get 45.875. when you put this number over 100 you get 45.875/100 or .45875. multiply by 100 to get your percent 45.875%, round, 46%, and thats your answer

Answer:

45.875%

Step-by-step explanation:

45 7/8 out of 100 meters

= ((45*8+7)/8)*(1/100)

= ((360+7)/8)*(1/100)

= (367/8)*(1/100)

= 367/800

=0.45875

=0.45875*100 (convert to %)

=45.875%
