Order these factions from the smallest to largest

7/10
3/4
2/5
1/2
2/3

what you have is

.7 , .75 , .4 , .5 , .67

so
2/5 , 1/2 , 2/3 , 7/10 , 3/4

7/8 0.333 1/9 3/5

To order these factions from smallest to largest, we need to compare their values. However, before doing so, we can simplify each fraction to its simplest form to make the comparison easier.

Let's simplify each fraction:

7/10 cannot be simplified further.
3/4 cannot be simplified further.
2/5 cannot be simplified further.
1/2 cannot be simplified further.
2/3 cannot be simplified further.

Now that we have simplified the fractions, we can compare them.

The simplified fractions are:
7/10, 3/4, 2/5, 1/2, 2/3

To compare these fractions, we need to find a common denominator. The least common denominator for these fractions is 20.

Now we can convert each fraction to have a denominator of 20:

7/10 = 14/20
3/4 = 15/20
2/5 = 8/20
1/2 = 10/20
2/3 = 13/20

Now let's order them from smallest to largest:

8/20 < 10/20 < 13/20 < 14/20 < 15/20

Therefore, the order from smallest to largest is:
2/5, 1/2, 2/3, 7/10, 3/4.
