Question

3. Order these values from least to greatest:
4/10, 1/3, 2/7, 6/10, 1 & 1/3, 2 & 7/10

Answer 1

lets give them all a common denominator, since it would be to hard for LCM, lets go with 210, 4/10=84/210, 1/3=70/210, 2/7=60/210, 7/10=87/210
so least to greatest: 2/7,1/3,1/3,4/10,7/10,1 and finally, 2

Answer 2

I find, with problems such as these, it is easier to turn them all into decimals then it is to mess with finding the common denominator and doing it that way.

4/10 = 0.4
1/3 = 0.33
2/7 = 0.29
6/10 = 0.6
1 1/3 = 1.33
2 7/10 = 2.7

so least to greatest is : 2/7, 1/3, 4/10, 6/10, 1 1/3, 2 7/10
