That would be 1/5 in simplest form you can divide both numbers by 12 and when you do you get 1/5. Hope this helps!
110 liters. 1000ml = 1 liter. Move the decimal 3 places to the left,so 110,000 ml becomes 110 liters.
Well,
1/5 of 1200 is 240
Then, you subtract 240 by 1200
So, you get $960
Unsure of what you mean by "reference number."
I do recognize that 11pi/9 is in quadrant III. I suspect that the so-called "reference number" is the acute angle between the end ray of 11pi/9 and pi, or, in more easily comparable numbers, between 9pi/9 and 11pi/9.
That difference is 2pi/9.
Tbh ion even kno this shii
