Hi I really need help with this question. SHOW YOUR WORK IF YOU ARE WILLING TO HELP ME TY! &lt;3
Ulleksa [173]

Answer:

8.9

Step-by-step explanation:

Parenthesis are always first so,

4.5+7.6=12.1

so the problem would look like this now:

12.1-8/2.5

so convert 8/2.5 to 8÷1/5÷2 so this will become 16/5

16.5 concerted to decimal=3.2

so 12.1-3.2=8.9
