Question

Express 0.6 + 0.7 + 0.47 bar in the form p by q where p and q are integers and q not equal to zero

Answer 1

Step-by-step explanation:

1)let x be 0.66...-1

10x=6.666....-2

subtracting 2from 1

10x-x=6.66-0.66

9x=6

x=6/9

2)let x be 0.7

repeat above process

9x=7

x=7/9

3)let x be 0.4747..

so,100x=47.47..

repeat process

99x=47

x=47/99

6/9+7/9+47/99

66/99+77/99+47/99

=190/99
