If the ratio of key to student council is 7 to 9, then the ratio of key to total is 7 to 16 and the ratio of student council to total is 9 to 16. If the total is 353, then the ratio equation would be,, {{{7/16=X/353}}} where X is the total number of key members in your total. {{{x=(353*7)/16}}} {{{x=154.4375}}} We round that value down to 154 since we can only have integer values. X=154
