\[2.3+3.7-2 \over27.5-4\times5.625\]
OpenStudy (solomonzelman):
First, multiply \(\large\color{black}{ \displaystyle 4\times 5.625 }\) on the bottom. What will you get?
OpenStudy (ilovecake):
22.5
OpenStudy (ilovecake):
so then I do 27.5-22.5?
OpenStudy (ilovecake):

27.5-22.5=5. Then what do I do.
OpenStudy (ilovecake):
so the answer is 4/5?
OpenStudy (solomonzelman):
what you have after this, is \(\large\color{black}{ \displaystyle \frac{2.3+3.7-2}{27.5-22.5} }\)
OpenStudy (solomonzelman):
now, subtract in the denominator.
OpenStudy (ilovecake):
I think the answer is 4/5

okay
OpenStudy (anonymous):
\[2.3+3.7-2 \over27.5-4\times5.625 \] First, you should add 2.3 and 3.7.
OpenStudy (ilovecake):
But is 4/5 the answer?
OpenStudy (anonymous):
What do you get as a result of the addition?
OpenStudy (solomonzelman):
yes, 4/5 is the answer.

basically it comes down to (6-2)/5
OpenStudy (solomonzelman):
as you have apparently noticed.
OpenStudy (anonymous):
Yes, 4/5 is the answer. (As SolomonZelman said!)
OpenStudy (ilovecake):
Yeah cause I did 3.7 -2 and then and then add 2.3.
OpenStudy (ilovecake):
okay thank you guys.

No problem! :)
OpenStudy (solomonzelman):
I was seeing more adding 2.3 and 3.7 which makes it 6, and then subtracting to.
Just how I visualized it...
