6.7 or 6 7/10

Step-by-step 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!

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
