Question

What is the percentage of 30 meters of 200 meters ?

Answer 1

Assuming you meant what percentage is `30` meters of `200` meters:
`color(white)("XXX")color(blue)(15%)`

Explanation:

`30` meters of `200` meters means
`color(white)("XXX")(30" meters")/(200" meters")`

`color(white)("XXX")=30/200 =3/20 =(3xx5)/(20xx5)=15/100`

That is `30` meters of `200` meters is `15` parts per `100` (or `15` per cent [since "cent" means "hundred"])
