HELLO MY DEAR FRIEND

8 MEN'S DO A WORK IN 39 DAYS

18 MEN'S DO A WORK IN HOW MANY DAY'S  = ?
                 
                               MEN'S                       DAYS

                                  8                                39
                                  4                                ?(Y)

NEXT STEP,CROSS MULTIPLICATION
 
LET'S TAKE NO OF DAYS = Y

= 8 MEN'S × Y = 4 MEN'S× 39 DAYS 

= 8 MEN'S ×39 DAYS = Y × 4 MEN'S 

Y = 8×39 / 4 

= 78/1 

= 78

             4  MEN'S CAN COMPLETE THEY WORK IN 78 DAY'S

I HOPE THIS WILL HELP'S U..............*-*
