Given :
Emily signed 2/5 of total cards
So, Cards signed by emily = 2/5 × 75
= 30 cards
Now, remaining cards = 75 - 30 = 45 cards
Now, josh signed 1/9 of the remaining cards
So, 1/9 × 45 = 5 cards
Remaining cards = 45 - 5 = 40 cards
Now, josh signed 20% of the remaining cards
= 20/100 × 40
= 8 cards
So, remaining cards = 40 - 8 = 32 cards
Hence, There are 32 cards cards yet to be signed.
