Yes you should. When using a system
Start with

Exponents have the highest priority, so we evaluate 3 cubed first:

Next, we have to solve parenthesis first: we have 27-8 = 19, so the expression becomes

Multiplications and divisions have the same priority, so we perform them as they appear:
, so the expression becomes

It should be 40%, you convert 18/45 to a decimal then multiply by 100
It’s b because I just did that question

? = 10*15/6
? = 25
