Explanation
To write the ratio of office workers to nonoffice workers, you need to first find the number of nonoffice workers. That is 359 – 62, or 297. You can write the ratio of office workers to nonoffice workers as 62:297. Try writing this ratio in lower terms by dividing both numbers by 62.
\((62 \div 62):(297 \div 62) = 1 \div 4.79\)
Since 4.79 is quite close to 5, the ratio is approximately 1:5.
