Select the proper order from least to greatest for 2⁄3 , 7⁄6 , 1⁄8 , 9⁄10 . a. 2⁄3 , 9⁄10 , 7⁄6 , 1⁄8 . b. 1⁄8 , 9⁄10 , 7⁄6 , 2⁄3 . c. 7⁄6 , 9⁄10 , 2⁄3 , 1⁄8 . d. 1⁄8 , 2⁄3 , 9⁄10 , 7⁄6 .

Know this?  Add apples to apples and oranges to oranges.
This problem becomes much easier if the fractions are converted to decimal fractions for comparison purposes:

2⁄3 , 7⁄6 , 1⁄8 , 9⁄10
are approx equal to 0.67, 1.17, 0.125, 0.90

So, rearranging these numbers in increasing order, we get 

0.125, 0.67, 0.90, 1.17.

We could go back to the originals:   1/8, 2/3, 9/10, 7/6.

Ithink the answer is: it is likely.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
