You have 3/4 cups of flour for your cake you need to add 5/6 more cups then you need to divide 2/3 cups for a different recipe solve in the simplest form

19/72 or 0.26388 ...

Step-by-step explanation:

Simplify the following:

((3/4 + 5/6) / 2) / 3

((3/4 + 5/6) / 2) / 3 = (3/4 + 5/6) / (2*3):

(3/4 + 5/6) / (2*3)

Put 3/4 + 5/6 over the common denominator 12. 3/4 + 5/6 = (3*3) / 12 + (2*5) / 12:

((3*3) / 12 + (2*5) / 12) / (2*3)

3*3 = 9:

(9/12 + (2*5) / 12) / (2*3)

2*5 = 10:

(9/12 + 10/12) / (2*3)

9/12 + 10/12 = (9 + 10) / 12:

((9 + 10) / 12) / (2*3)

9 + 10 = 19:

(19/12) / (2*3)

(19/12) / (2*3) = 19 / (2*3*12):

19 / (2*3*12)

2*3 = 6:

19 / (6*12)

6*12 = 72:
