Dilution, solution, ratio, proportion (laboratory. calculations)

A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. ... Since the cross products are both equal to one hundred, we know that these ratios are equal and that this is a true proportion. #Proportion #ratio #solvent #diluent #solution #dissolve #laboratoryCalculations
