What is the percentage of 30 meters of 200 meters ?

1 Answer

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

Explanation:

$30$ $30$ meters of $200$ $200$ meters means
$XXX \frac{30 meters}{200 meters}$ $color(white)("XXX")(30" meters")/(200" meters")$

$XXX = \frac{30}{200} = \frac{3}{20} = \frac{3 \times 5}{20 \times 5} = \frac{15}{100}$ $color(white)("XXX")=30/200 =3/20 =(3xx5)/(20xx5)=15/100$

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