explain what?
OpenStudy (anonymous):
Alright, so let's use Order of Operations to solve this. First, let's use the parentheses first. So multiply 62 by 1/2 and then add 5.
OpenStudy (anonymous):
idk how to solve like the 1/2 part i know how to do the rest just not the 1/2
OpenStudy (anonymous):
Multiply 1/2 by 62. So take half of it.
OpenStudy (anonymous):
that means times
\[\frac{1}{2}\times 64\]

Parentheses means Multiply.
OpenStudy (anonymous):
so the answer is 31?
OpenStudy (anonymous):

OpenStudy (venomblast):
the question can be confusing for some people because to me that is just saying 2 * 64.

OpenStudy (anonymous):
So just use the same process.
OpenStudy (anonymous):
You can actually divide 261 by 3.
OpenStudy (anonymous):
So divide it by the denominator and multiply that result as a numerator.
Then subtract 9.
OpenStudy (anonymous):
oh so hold on let me solve it and then you check it
