Evaluate. MEDAL+FAN.

OpenStudy (ilovecake):

\[2.3+3.7-2 \over27.5-4\times5.625\]

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):

???

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

Ok. Let's start over.

OpenStudy (ilovecake):

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.

OpenStudy (solomonzelman):

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.

OpenStudy (anonymous):

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...
