Answer: do you mean which is the closest? If so that would be mars
Step-by-step explanation:
The answer is 2/100 or 1/50!
6/10 is equivalent to 60/100.
62/100 - 60/100 = 2/100 = 1/50
So, 6/10 + 1/50 = 62/100
6/10 + 2/100 = 62/100
(Use 1/50 because that’s the simplified answer!)
I hope this made sense! Good luck!
Answer:

Step-by-step explanation:
If there are <em>n</em> students, then the number of pairs is
.
With 12 students,
pairs can be formed.
The reason the formula works is this: Each of the 12 students can be paired with 11 other students (no student is paired with him/her self). But counting 12 x 11 = 132 counts each pair <u>twice</u>. Example: student A can be paired with student B,..., student B can be paired with student A. The pair was counted two times.
See the attached image that shows pairings of 5 students. There are
5(5 - 1)/2 = 5(4)/2 = 10 pairs.
