A training certificate composed on a personal computer that was designed to be nine inches long and six inches wide has to be proportionately enlarged so that its length will be 12 inches. How many inches wide will the enlarged certificate be?
Suggested Answer:C🗳️
Since the certificate and its enlargement are similar (i.e., proportional) figures, the lengths will have the same ratio as the widths; if the length is increased by a given proportion, then the width will be increased by the same proportion or percentage of its original size.
It is 8 inches because if the width is proportionally converted according to the length which was 9-12 inches you subtract 12 by 9 and you get 3 which you divide by 9 to get 1/3 then you get 1/3 of the width which is 6 inches and you would get 2 and you add 2 plus 6 which is 8 inches.
