Express the following as a fraction in simplest form :

1.6

We have:

1.6

There is 1 decimal place, so we remove the decimal point and divide by 10.

$\phantom{=} 1.6 = \dfrac{16}{10} \\[1em] = \dfrac{8}{5} \quad \text{[Dividing both by 2]} \\[1em] = 1\dfrac{3}{5}$

∴ The answer is $1\dfrac{3}{5}$
