Question

Danny has 42 saplings. He plants them equally in 8 rows. How many saplings are left over?

Answer 1

2

Explanation:

If he plants `x` saplings per row, then
`8x <= 42`

`x` has to be a whole number and cannot be in fraction, as it represents number of saplings.

The multiple of 8 closest to 42 is 40, that is, when `x =5`.

Therefore, if 40 saplings are planted (5 saplings in each of the 8 rows) then 2 are left out.
