Put 12/15,3/5,7/15,3/7 in smallest to greatest order

12/15,7/25,3/7,3/5 should be correct because this is what my teacher taught me in fourth grade.

3/7, 7/15, 3/5, 12/15

Step-by-step explanation:

You have to find the common denominator; which is 105

So the equations turn into

12/105 , 3/105, 7/105, 3/105

Then you divide the old denominator with the new denominator.

105/15= 7, 105/5=21, 105/7=15

You then multiply that number with the numerator so:

84/105, 63/105, 49/105, 45/105

Then order accordingly!
