-9 - 11 = -20
11/6 minus 2/9 is 1 11/18
No eleven is not IX, it would be XI. The lower symbol in front of a larger one means to subtract, in this case it is nine (9).
11 + (n/2) = 77 Subtract 11 from both sides: n/2 = 66 Multiply both sides by 2: n = 132
Eleven and eleven thousandths.

Subtract the lowest from the highest: 11,000,000-8,000,000 = 3,000,000
No eleven is not IX, it would be XI. The lower symbol in front of a larger one means to subtract, in this case it is nine (9).
11 + (n/2) = 77 Subtract 11 from both sides: n/2 = 66 Multiply both sides by 2: n = 132
Eleven and eleven thousandths.
It is 11,12,111
You need to do two changes before you can do the actual subtraction. One, since 2/3 is more than 1/2, you have to write 11 1/2 as 10 3/2. That is, you add 2/2 to the fractional part, and, to compensate, you subtract the equivalent (2/2 = 1) from the integer part. Two, you have to convert the fractions to a common denominator. Once you have done these two changes, you can easily subtract. (Subtract the integer part and the fractional part separately.)
