Answer: Since her art and music sections each only had half the number of sheets of paper as a core subject, together the two sections had the same amount of paper as a core subject. Therefore, it is almost like her notebook had five core subjects, rather than four core subjects and two electives. If she divided the 200 sheets equally among the five core subjects, there would be 200 ÷ 5 = 40 sheets in each section. Now we can see that art would actually have half of this amount, or 20 sheets of paper.
For this case we must follow the following rules of rounding
1) If the previous number is greater than or equal to five, then the next number increases by one unit
2) If the previous number is less than five, then the next number stays the same
Therefore, the steps for rounding to the nearest tenth is:
1) We observe that 3 is less than 5.
2) Therefore, the next number stays the same
Rounding to the nearest tenth is:
5.6
Answer:
1) We observe that 3 is less than 5.
2) Therefore, the next number stays the same
5.6
