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
