Question

How do you order these numbers from least to greatest: `3.646,3.64,\frac { 63} { 20} ,3\frac { 1} { 10}`?

Answer 1

See a solution process below:

Explanation:

First, convert the fraction to a decimal number:

`63/20 = (60 + 3)/20 = 60/20 + 3/20 = 3 + 0.15 = 3.15`

Next, convert the mixed number to a decimal number:

`3 1/10 = 3 + 1/10 = 3 + 0.1 = 3.1`

We can now order these numbers as:

`3.1"; "3.15"; "3.64"; " 3.646`
