Question

Express 0.7 bar + 0.5+0.91 bar in the form of p/q​

Answer 1

Answer:

(1) 0.77777 => X

Multiply On both sides by 10

7.77777 => 10X

Subtract first equation from second equation,

7=9X =>X= 7/9

(2) 0.919191919191 => Y

Multiply on both sides by 100

91.919191919191 =>100Y

Subtract first equation from second equation,

91=99Y => Y = 91/99

So we need add 7/9 +1/2 + 91/99 LCM of all denominators is 198 So

7*22+99+91*2/198 => 435/198 => 145/66

p/q = 145/66

Answer 2

Answer:

7/9+1/2+91/99= 145/66
