7.5% of 160.
12 / 160 = 0.075
Move decimal 2 places to the left to convert it to a percent, or multiple by 100.
0.075 * 100 = 7.5
7.5% is your answer.
Remember to do PEMDAS so your answer is not correct, since you multiplied before doing the parentheses/exponents.

Whats the equation...............
In this question, we are given a matrix, and we have to perform the given operation.
The matrix is:
![\left[\begin{array}{ccc}6&-1&|5\\1&-5&|0\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D6%26-1%26%7C5%5C%5C1%26-5%26%7C0%5Cend%7Barray%7D%5Cright%5D)
The following operation is given:

In which
is the element at the first line and
is the element at the second line.
Updating the first line:



Thus, the filled matrix will be given by:
![\left[\begin{array}{ccc}0&29&|5\\1&-5&|0\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D0%2629%26%7C5%5C%5C1%26-5%26%7C0%5Cend%7Barray%7D%5Cright%5D)
