25.62 is the money he had overdrawn
45 is the money money charged buy the bank for overdraft fee
So the Total balance to the bank is

because you need a number smaller than 10
next you just count how many times from the decimal till you get the number you are looking for
The exact value on sin82.5 is : 0.99144486137381041114455752692856. (And yes, that is the exact value of it. All you would have to do is go to the nearest calculator, put in the number, and then press the sin button, and there you go. There's your answer.
Assume that there are 100 students in the class.
(Working with numbers is easier than working with percentages).
There are 27 students who passed both tests, and 51 who passed only the first test.
The 27 students who passed both tests are included in the 51 who passed the first test.
We are asked "What percent of those who passed the first test also passed the second test?"
so we are asked "what percent of 51 is 27?"
let 51 be 100%
then 27 is
![\frac{27*100}{51}](https://tex.z-dn.net/?f=%20%5Cfrac%7B27%2A100%7D%7B51%7D%20)
%=52.941%
Answer: 52.941%
