Last year, the number of students enrolled in school was 847 if this number increases by 9% the next year, how many students will there be

924

Step-by-step explanation:

The number of students this year will be increased by 9%, so that means you'll have to multiply by 1.09 (109%). This means you take 847 * 1.09 = 923.23 students, which you then round up (because you cannot have a decimal of a student) to 924.

all of the measures need to be converted to the same measure; such as inches. if you do that it is easy to determine which is the longest, 2500 mm which is approximately 97.5 inches.
