We can't tell where the parentheses belong in the question.
Here are the answers for both possibilities:
(1/2) + 0.2 = 0.7
1 / (2 + 0.2) = 0.4545 ... (repeating)
1 over 3 plus 1 over 12 equals 5 over 12
The answer to 1 over 2x plus 13 equals 9 is x equals -8.
It is: 1/3 plus 1/3 = 2/3
It equals 2 over 8.
That equals 1/4.
1 and 2/5
it equals 8 over 8 or 1 =1
1/5 plus 1/5 which equals 2/5 or 0.4.
-1
1/2 + 1/6 = 2/3
0.9375 or 15/16
