    Answer:

    8/10+7/9+39/90

    Step-by-step explanation:

    expressing something in the form p/q means basically make it a fraction.

    .8 = 80/100

    .7bar= .77777777777 (7/9)

    0.43 (bar on 3 only is)= 0.433333333333333

    how to make a fraction for .777777bar

    10x = 7.777777777

    X = .7777777777

    subtract 10x-x  

    we get 7/9 for .7777 (10x-x = 9 thats the denominator and, 7.7777-.7777 = 7.)

    how to make a fraction for .43bar for 3 only

    100x = 43.3333333333

    10x = 4.33333333333

    100x-10x = 43-4

    43-4 = 39, and the 333333333 cancel out 39/90
