Percentage means the tenth place so it has to be 90%
Answer:
for a it would be 11/18 and for b it would be 4/9
Step-by-step explanation:
This is because I did the same butterfly method. 5 times 5 times 18 which is 90 for 5/9 and 9 times 18 is 99 for 11/18, you can also write it as 5/9 and 11/18 but cross multiply. This is also what I did with the second one.
