there is a 5.7 kilogram mixture of rice, wheat, and corn.
if wheat = 2.1 kg and is equal to 7 units in the ratio.
then 2.1 divided by 7 = 0.3kg
that means 1 unit if equivalent to 0.3kg
if there are 3 units of rice, 7 units of wheat, and 9 units of corn in the ratio, then that means there are 19 units in total.
19 units multiplied by 0.3kg = 5.7 kg
