Question

Julia has a mask collection consisting of 255 masks she keeps on the wall and 45 she keeps in a display case. What percentage of Julias mask collection does she keep on her wall?

Answer 1

We are told that Julia keeps 255 masks on the wall and 45 on the display case, this means in total the number of masks she has is

`255+45=300\text{masks}`

The number of masks Julia keeps on the wall is 255 masks; therefore, the percentage of fo masks on the wall is

`(255)/(300)*100`
`=85.\text{ }`

Hence, Julia keeps 85% of her mask collection on her wall.
