Given:

Saili plants 4 saplings, in a row, in her garden. The distance between two adjacent saplings is $\frac{3}{4}\ m$.

To do: 

We have to find the distance between the first and the last sapling.

Solution:

The distance between two adjacent saplings $=\frac{3}{4}\ m$.

The distance between the first and second sapling $=\frac{3}{4}\ m$.

Similarly,

The distance between the second and third sapling $=\frac{3}{4}\ m$.

The distance between the third and fourth sapling $=\frac{3}{4}\ m$.

Therefore,

The distance between the first and fourth sapling $=\frac{3}{4}+\frac{3}{4}+\frac{3}{4}\ m$.

$=\frac{3+3+3}{4}\ m$.

$=\frac{9}{4}\ m$.

The distance between the first and the fourth sapling is $\frac{9}{4}\ m$.
