Question

A farmer has 1235 trees to be planted on a rectangular parcel of land. If there are 24 trees planted in each row and each row must be complete before it is planted, how many trees will be left over after planting?

Answer 1

We have 1235 trees.
In each row is 24 trees.

Divide the number of trees by the maximum number in a row:


`(1235)/(24)=51(11)/(24)`

We see that the maximum can be 51 rows, next we rounding down to the nearest value (51).

We check how many trees will remain:

1235 - 51 * 24 = 11

11 trees will remain vacant.
