Fractions and Percent problem.I have to write each ratio as a percent.

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

Answers

Answer 1
Answer: 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 2
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%

Answers

Answer:

0.5 or 1/2

Step-by-step explanation:

The answer is 0.5 or one half, because you are trying to figure out the amount of other students who have participated. So we know that 29 out of 58 participated, so you just do 29/58 and you get 1/2.
