The Smiths are sending out a batch of holiday cards. Emily signed of the cards. Then Josh signed of the remaining cards. Tatiana signed 20% of what Josh had left. If there were 75 cards in all, how many cards are left to be signed?

There are 32 cards left to be signed

Step-by-step explanation:

Hi, the correct question is:

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. If there were 75 cards in all, how many cards are left to be signed?

So, to answer this question:

Emily signed 2/5: so, we have to multiply the number of cards (75) by the amount that she signed:

Then, we subtract the result to the total amount of cards:

Repeating the process with Josh (now the total number of cards is 45)

And finally we repeat the process with Tatiana ( using the decimal form of 20% ⇒ 20/100= 0.2)

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6
