put in order from greatest to least 3/6,5/6,4/10.

3/6= 15/30
5/6= 25/30
4/10= 12/30
So it's 4/10, 3/6, 5/6 
how did u get 30?

Sorry, I accidentally did least to greatest. It is 5/6, 3/6, 4/10

30 is the least common denominator of 6 and 10
6 = 2 *3
10 = 2*5
to make them the same I must multiply 6 by 5 and 10 by 3
6*5 = 2*3*5 = 30
3*10 = 2*5*3 =30 
The ones with the denominators of 30 are just equivalent fractions. Per see, 6 goes into 30 5 times. So you multiply the numerator, 3, and the denominator, 6, 5 times. Same with 5/6, just the 3's a 5 there. 4/10 is equivilent to 12/30, because you multiply 10 3 times to get there. So you multiply 4 3 times also. Get it?
