Mathematics

Answer:

100

Step-by-step explanation:

In this problem 10 represents 9% of a number. So, to find 90% you must multiply 10 by 10. You do this because 9% times 10 equals 90%; therefore, 100 must be 90%.

This can also be proven through cross multiplication. To set up a proportion put the percent over the number like, \frac{9}{10}=\frac{90}{x}. Then cross multiply to get the equation, 9x=900. Finally, divide both sides to get x=100.

If there are 100 tickets to a concert and 200 fans who would like to go to the concert, each placing a slightly different value
Setler79 [48]
It's more efficient to hold a random drawing because the probability is higher.
\frac{100}{200}  =  \frac{1}{2}
For every 2 person, 1 person gets to go to the concert.

Answer is 1/2 aka 0.5 aka 50%

Hope this helps. - M
