They need a common denominator. so the common denominator is 8. so multiply the 3 and the 4 each by 2. so then you get 6/8. then subtract 1/8 from 6/8. so it looks like 6/8-1/8 and you'll get an answer of 5/8.
A: 25.12 (26 if your rounding)
B: You have to multiply R by 2 then by pi (3.14)
C: 10.5 (11 if your rounding)
Step-by-step explanation:
For a: A circle's circumference is its diameter multiplied by pi (3.14) To get the diameter you would multiple the radius by 2. Therefore your answer being 25.12 (Round to 26 if you want)
For c: Divide 65 by pi then that answer by two.

The total number of handshakes was 234.
- The first man shook hands with 12 other men.
- The second man shakes hands with 11 other men, as he had already shaken hands with the first man.
- Like-wise, the last man does not need to shake hands again as every man has already shaken hands with him in their respective turns.
- The number of handshakes among men is 0 + 1 + 2 + … + 12.
- The sum of "n" natural numbers = (n)(n+1)/2
- The number of handshakes among men is 12(13)/2.
- The number of handshakes among men is 78.
- Each man shakes hands with every woman except his spouse.
- Each man shakes hands with 12 other women.
- The number of handshakes between men and women is 13*12.
- The number of handshakes between men and women is 156.
- The total number of handshakes is 78 + 156.
- The total number of handshakes is 234.
