All of the following are true statements about common fractions and ratios except for: Group of answer choices common fractions do not require labels for each of their parts like ratios do. neither common fractions nor ratios can have zeros in the denominator (common fraction) or second position (ratio). ratios can have parts added to them such as when the ratio of boys to girls in a class changes when new students add the class; common fractions cannot. ratios are not independent numerical expressions and must be understood in the context of the relationships they represent; common fractions are independent of context
