What set of fractions is ordered from least to greatest? A) 2/5,1/4,3/8 B) 3/8,2/5,1/4 C) 1/4,3/8,2/5 D) 3/8,1/4,2/5
LenaWriter [7]

Answer:

C) 1/4,3/8,2/5

Step-by-step explanation:

First of all, let's rewrite all the fractions listed as decimal numbers:

\frac{2}{5}=0.400

\frac{1}{4}=0.250

\frac{3}{8}=0.375

So the correct order from least to greatest should be

0.250, 0.375, 0.400

Which corresponds in fractional form to

1/4, 3/8, 2/5

So the correct option is

C) 1/4,3/8,2/5
