Mrs. Wilkerson cut some oranges into 20 equal pieces for 6 friends and how many did they get, how many were left over?
So...
6x=20
x represents how many oranges did the friends get each.
The number that multiplied 6 is 6x2=12 6x3=18.
18 is close to 20, so 20-18=2
There are 2 pieces of the orange left.
Hope that helps.
