<u>Answer:</u>

<u>Step-by-step explanation:</u>
Maria ate a quarter of a whole pie = 
Left over pie = 
Edwin ate 1/3 of what was left = 
Left over pie = 
Cristina ate 1/3 of what was left = 
Left over pie = 
After Martha ate 1/4 of the pie there is 3/4 left.
Edwin ate 1/4 of 3/4.
so multiply 1/4 and 3/4 ---> 1/4*3/4=3/16
to find the leftover subtract 3/16 from 3/4
3/4-3/16
12/16-3/16=9/16
Christina ate 1/3 of 9/16
multiply 1/3 by 9/16
1/3*9/16=3/16
find the leftover by subtracting 3/16 from 9/16
9/16-3/16=6/16
divide by 2
3/8
