0.4bar​

Answer 1

Step-by-step explanation:

let 0.5888...=x

multiply by 10

5.8888....=10x

multiply by 10

58.888...=100x

subtract by 10x

53=90x

$\binom{53}{90} = x$

let 0.867777...=x

multiply by 100

86.777...=100x

multiply by 10

867.777...=1000x

subtract by 100x

790=900x

$\binom{790}{900} = x \\ \binom{79}{90} = x$

let 0.444....=x

multiply by 10x

4.444....=10x
