Answer 2

HEY MATE HERE IS YOUR ANSWER

12)

lets convert hour in to minutes

so A worked 3/5 × 60

= 3 × 12

= 36 minutes

and B worked 7/10 × 60

= 7 × 6

= 42 minutes

so B worked longer in time.

to find fraction of time taken longer we can do this (42 - 36)/60

=6/60

=1/10

13) in this sum take common

5792 × 983 - 4792 × 983

= 983 (5792 - 4792)

= 983 (1000)

= 983000
