Answer 1

5:4 your welcome ttmer

Answer 2

Find out the ratio of sharpened pencils to unsharpened pencils .

To proof

As given

In a box of 36 pencils, 20 are sharpened

Number of unsharpened pencil = 36 -20

= 16

Now find out the ratio of sharpened pencils to unsharpened pencils .

`(sharpened\ pencil)/(unsharpened\ pencil) = (20)/(16)`

simplify

`(sharpened\ pencil)/(unsharpened\ pencil) = (5)/(4)`

Therefore the ratio of sharpened pencils to unsharpened pencils is 5 :4 .

Hence proved
