Any multiple of 27720
Fill 7 Pour out into 11 Fill 7 again Pour out into 11: only 4 will go in leaving 3 in the 7 Empty out 11. Pour 3 from 7 into 11. Fill 7 yet again. Pour out into 11 where you will now have 10 ounces.
The LCM is 770.
To find the mean you would add up all the numbers 7+9+10+11+11+12 and get 60. Then divide by how many numbers you added by, in this case 6. So 60 ÷ 6 = 10. The mean would be: 10
(18 + 18 + 11 + 7 + 6 + 11 + 10 + 20 + 7)/9= 12========The mean, also often called the "average", is1/9 of (18 + 18 + 11 + 7 + 6 + 11 + 10 + 20 + 7)
7 + 8 + 10 + 11 = 36 / 4 = 9
The average is 10... 11+11+9+7+12=50... 50/5=10
Fill 7. Pour all into 11. Fill 7 again. Pour to top-up 11. 3 litres left in 7. Empty 11. Pour remainder (3) from 7 into 11. Fill 7 again. Pour into 11. The 11 container now has 10 litres in it.
The LCM of 5, 7, 10, and 11 is 770
16 10/11 - 9 = 7 10/11
For X, I assume. 7X - 10 = 4X + 11 subtract 4X from each side 7X - 4X - 10 = 4X - 4X + 11 3X - 10 = 11 add 10 to each side 3X - 10 + 10 = 11 + 10 3X = 21 divide both sides by 3 X = 7 check 7(7) - 10 = 4(7) + 11 49 - 10 = 28 + 11 39 = 39 checks
There are infinite numbers, but a fine example is just 7*8*10 or 560
The LCM is 6930.
