Ten and four elevenths.
-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).
An eleven year old should be able to do this kind of maths. 2010 to 2040 is 30 years ( subtract 2010 from 2040). Ad 30 years to 11 answer is 41. An eleven year old will be 41 in 2040
11 + (n/2) = 77 Subtract 11 from both sides: n/2 = 66 Multiply both sides by 2: n = 132
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.)
