Name three ratios that are equivalent to 5:2

The threes ratios that are equivalent to 2 to 5 are : 2* 2/5 *2 4/ 10 3*2/ 5*3= 6/ 15. 4 * 2 / 5 * 4= 8/ 20.

step-by-step explanation:

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
