How do you round 5 1/8 to the nearest whole number
2 answers:
When you are rounding always remember this rule
0-4 stay on the floor ( stick with the whole number)
5-9 climb the vine (increase one number)
BUT for fractions you have to make the denominator 100 before you can round
1/8 is equal to 0.5/4
multiply 0.5 times 25 and 4 times 25 so 100 is your denominator
which gives you 12.5/100
since 12.5 isn't 5 to 9 you stay on the floor
when i say 5 to 9 and the denominator is 100 its new value becomes 50-90
So, your answer is 5!

Answer:
140
Step-by-step explanation:
To construct a subset of S with said property, we have two choices, include 3 in the subset or include four in the subset. These events are mutually exclusive because 3 and 4 can not both be elements of the subset.
First, let's count the number of subsets that contain the element 3.
Any of such subsets has five elements, but since 3 is already an element, we only have to select four elements to complete it. The four elements must be different from 3 and 4 (3 cannot be selected twice and the condition does not allow to select 4), so there are eight elements to select from. The number of ways of doing this is .
Now, let's count the number of subsets that contain the element 4.
4 is already an element thus we have to select other four elements . The four elements must be different from 3 and 4 (4 cannot be selected twice and the condition does not allow to select 3), so there are eight elements to select from, so this can be done in ways.
We conclude that there are 70+70=140 required subsets of S.
