If 30 men can plant a 100 trees in 9 days, how long does it take for 36 men
to plant 4400?
30 men can plant 100 trees in 9 days,
If we divide the number of men by 5 we must multiply the
number of days by 5, so
6 men can plant 100 trees in 45 days,
For 6 men to plant 4400 trees, it will take 44 times as long, so
6 men can plant 4400 trees in 1980 days,
If we multiply the number of men by 6 to get 36 men, we must divide
the number of days by 6. So
36 men can plant 4400 trees in 330 days,
