Answer:
6.7 or 6 7/10
Explanation:
You'll be using PEMDAS. First, parenthesis.
(5.2+6.3) this is equal to 11.5
Since you don't have any exponents, you'll move on to multiplication and division, so -12÷2.5. This equals -4.8.
(When you divide any number by a negative number, the result will be negative)
Now you're left with 11.5-4.8, which equals 6.7.
This is what it would look like written out:
(5.2+6.3)-12÷2.5
11.5-12÷2.5
11.5-4.8
6.7
Hope this helps!
