Write the fractions from least to greatest.

4/6, 7/12, 5/10

The answer would be 5/10, 7/12, and then 4/6
How: What you will do is fine the common denominator between the fractions, which is 60. 
5/10: Multiply numerator and denominator by 6 to get, 30/60. 
7/12: Multiply numerator and denominator by 5 to get, 35/60.
4/6: Multiply numerator and denominator by 10 to get, 40/60.
HOPE THIS HELPS YOU! ^_^

Just divide the x axis (the top) by 2 or multiply the y axis (the bottom) by 2

Ithink the right answer could be 50%
