How can I solve this problem? 4/6 minus 2/9?

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
