Answer 1

Answer:

0.4761 = 4761/10000

0.7569 = 7569/10000

4761/10000 + 7569/10000

= 4761+7569/10000

=12330/10000 = 1233/1000 ( 0s get cancelled)

7569/10000 - 4761/10000

= 7569 - 4761/10000

= 2808/10000

1233/1000 divided by 2808/10000

= 1233/1000 × 10000/2808 ( reciprocal )

= 4.39 ( approximately)
