Answer:
23/36 of the package is left.
Step-by-step explanation:
you need 1/4 and 1/9 to have a common denominator.
for 1/4 multiply the top and bottom by 9 to get 9/36
for 1/9 multiply top and bottom by 4 to get 4/36
add them together and get 13/36.
now subtract the 13 from 36 to get 23. Put if over 36 and get 23/36
