Question

least to greatest 2.3 2 4/5 2.6

Answer 1

2.3 is smaller than 2.6: we can see it just by looking at the digits from left to right.

now, where does 2$\frac{4}{5}$ stand?

 its fraction part is equal to

$\frac{4*2}{5*2}= \frac{8}{10}$

do that means that 2$\frac{4}{5}$=2.8

which is bigger than 2.6

so the final order is

2.3 2.6 2$\frac{4}{5}$
