Verified Answer :

First change them all into fractions or decimals. Decimals a probably the easiest.
1/5= 0.2   12/25= 0.48  4/5= 0.8   
Order: 0.2, 0.35, 0.48, 0.5, 0.8
Then you change the decimals that you converted back into the fraction form.
Answer:  1/5, 0.35, 12/25, 0.5, 4/5

Answer:

\(\frac{1}{5}\), 0.35, \(\frac{12}{25}\), 0.5, \(\frac{4}{5}\)

Step-by-step explanation:

We have to arrange these numbers in least to greatest.

0.5, \(\frac{1}{5}\), 0.35, \(\frac{12}{25}\), \(\frac{4}{5}\)  

First we convert all the fractions in decimal numbers by dividing the numerator by denominator.

\(\frac{1}{5}\)  = 0.2

\(\frac{12}{25}\) = 0.48

\(\frac{4}{5}\) = 0.8

Now we can easily arrange the numbers in least to greatest.

0.2, 0.35, 0.48, 0.5, 0.8

or

\(\frac{1}{5}\), 0.35, \(\frac{12}{25}\), 0.5, \(\frac{4}{5}\)
