Line SW is perpendicular to line RS, but not to line TV
Note that they together ate all of the pizza.
Therefore the total fractions they ate should add up to 1.
By letting the fraction Jodie ate be x.
x + 2/5 + 1/4 = 1
x = 7/20
The answer is 7/20.
I believe that x is equal to 6. x=6
12/13 I believe :) hope it helps
