Given : The Smiths are sending out a batch of holiday cards.
Emily signed 2/5 of the cards.
Then Josh signed 1/9 of the remaining cards.
Tatiana signed 20% of what Josh had left.

To Find : how many cards are left to be signed?
Solution:
Total card = 75
Emily signed = (2/5) 75 = 2 * 15 = 30
Remaining = 75 - 30 = 45
Josh signed 1/9 of the remaining cards.
Josh signed = (1/9) 45 = 5
Remaining card = 45 - 5 = 40
Tatiana signed 20% of remaining
= (20/100) 40
= 8
Cards are left to be signed = 40 - 8 = 32
32 cards are left to be signed
