3 plus 27 divided (4 plus 5) 1/3 plus 2/5

3 + 27 / (4 + 5) = 6

1/3 + 2/5 = 11/15

Step-by-step explanation:

(4 + 5) = 9

27/9 = 3

3 + 3 = 9

1 x 5 = 5

3 x 5 = 15

5/15

2 x 3 = 6

5 x 3 = 15

6/15

5/15 + 6/15 = 11/15

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
