Question

Devonte is studying for a history test. He uses 1/8 of a side of one sheet of paper to write notes for each history event. He fills 2 full sides of one sheet of paper. Which expression could be used to find how many events Devonte makes notes for? Barry chose D as the correct answer. How did he get that answer?

Answer 1

The total amount of space Devonte uses to write notes on a single sheet of paper is 2 sides x 1 sheet of paper = 2/1 = 2.

And, for each event, he uses 1/8 of a side of the paper. Therefore, the number of events he writes notes for can be found by dividing the total amount of space he used by the amount of space used for each event:

Number of events = Total space used / Space used per event

We can substitute the values we know:

Number of events = 2 / (1/8)

Simplifying this expression by multiplying the numerator and denominator by 8, we get:

Number of events = 2 x 8/1

Number of events = 16

Therefore, Devonte made notes for 16 historical events. Option D, 16, is the correct answer.
