Question

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?

Answer 1

Are there any answer choices?

Answer 2

No.

Answer 3

Ok so since Emily signed 2/5 of the cards, we have to multiply (75) by the number that was signed so

75x2/5=30 75(2/5)=30

Now, we have to subtract so,

75-30=45 so, 45 cards are left unsigned

Then, we have to do the method we did first again which is ^^ but the numbers will change since the new total number is 45 so,

45x 1/9= 5 then,
45-5= 40

Now, we have to do the second step again in decimal form . . .

20% = 20/100 = .2 so, now

40x0.2=8
40-8=?
Tell me if that doesn't make sense or if you need more help.
