7*5=35 35 divide 5= 7
x = -5/3
The mean is 6.To get this answer you first add 5 and 7 which equals 12.Then you divide by how many numbers you added which is two.so you divide 12 by 2 which equals 6.
divide both numbers (if even, as in your case) by 2. It equals 3/15. Since you can continue, divide again, but this time, they are both divisible by 3, so divide by 3. It equals 1/5. Since you can no longer divide evenly, 6/30 simplified is 1/5. or, a faster way is divide 6/30 by 6. It still equals 1/5.
Divide 3.25 by 5 and get .65
