Question

Pedro cut a sheet of poster board into 10 equal parts. His brother used some of the poster board and now 8/10 is left. Pedro wants to make a sign from

each remaining part of the poster board. How many signs can he make?

Answer 1

out of the 10 his brother took two sheets out of the 10 that would leave him with 8 out of 10,left

Answer 2

Answer: 8

Explanation:

Given: Pedro cut a sheet of poster board into 10 equal parts.

let x be the total sheet.

then, one part of sheet=
`(1)/(10)` of the sheet

Now, His brother used some of the poster board and now 8/10 is left.

Therefore, if Pedro wants to make a sign from each remaining part of the poster board.

then, The number of signs he can make=
`(8)/(10)/ (1)/(10)=(8)/(10)*(10)/(1)=8`

Hence, Pedro can make 8 signs.
