Size of a Stadium

Explanation:

The size of the nucleus of an atom is around of the size of the atom. If the model of the atom is equal to Earth the size of the nucleus will be of the size of the Earth.

Radius of Earth = 6378 km = 6378000 meter

Radius (R) of nucleus will be,

Thus, it will be equal to the size of a stadium.

i don't understand. explain it clearly

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
