SPICY--Try if you have time.
Climate--With world temperatures steadily increasing, glaciers (large blocks of ice) in the sea are starting to melt, which affects sea levels and causes problems for island nations. One large glacier lost a total of 200 millimeters over 15 years.
Write a division equation to show the average change in the glacier's height each year. (Copy and paste division here: ÷ )
