Question

express 0.64+0.8bar +0.9 bar in the form of p/q where p and q are integers and q 0​

Answer 1

Answer:

2x+3;x;9−3x

2x+3;x;3x−9

x;2x+3;3x−9

2(x+3);x;9−3x

Answer 2

Answer:

2276/900

Step-by-step explanation:

=> Let x = 0.8[bar]                  (1)

=> Multiplying eq (1) with 10 on both sides

=> 10x = 8.8[bar]                    (2)

=> 10x - x = 8.8[bar] - 0.8[bar]

=> 9x = 8

=> x = 8/9

=> Let y = 0.[bar]                    (3)

=> Multiplying eq (3) with 10

=> 10y = 9.[bar]                       (4)

=> eq (4) - (3)

=> 10y - y = 9.9[bar] - 0.9[bar]

=> 9y = 9

=> y = 9/9

=> 0.64 = 64/100

=> 0.64 + 0.8[bar] + 0.9[bar] = 64/100 + 8/9 + 1

=> (576 + 800 + 900)/900 = 2276/900
