Question 135232
Let x=number of loaves of bread that Sara gives Jane

Then Sara gives Judy 3x loaves

Now we are told that the total amount of loaves is 12,
so:

x+3x=12
4x=12  divide both sides by 4
x=3 ----------------number of loaves of bread that she gives Jane

3x=3*3=9-----------------number of loaves that Judy gets

CK
9+3=12
12=12
and
9=3*3
9=9

Hope this helps---ptaylor
