Order the following from least to greatest 0.3 3/5 0.66 2/3 0.35

Change the fractions to decimals.

3/5 = 0.6

2/3 = 0.6667

Therefore,

0.3, 0.35, 3/5, 0.66, 2/3

To order the given numbers from least to greatest, we need to compare their values.

First, let's rewrite the given numbers as decimals to make the comparison easier:
0.3, 0.6, 0.66, 0.67, 0.35

Next, we'll compare the first two numbers, 0.3 and 0.6. It's clear that 0.3 is less than 0.6.

Now, let's compare 0.3 with 0.66. We can see that 0.3 is less than 0.66.

Next, we'll compare 0.3 with 0.67. Again, 0.3 is less than 0.67.

Finally, let's compare 0.3 with 0.35. We can see that 0.3 is greater than 0.35.

Therefore, the numbers in order from least to greatest are:
0.3, 0.35, 0.66, 0.67, 0.6

(Note: In the original list, 3/5 and 2/3 are equivalent to 0.6 and 0.67, respectively. However, since we were instructed to compare decimals, we have converted them.)
