Since the original cost is 2700, the fraction 1890 is of 2700 is 1890/2700. Since they both have a 0 at the end, we can cross that out to get 189/270. Next, since their digits add up to factors of 3 (1+8+9=18 and 2+7=9), we can factor 3 out to get 63/90. Repeating the process since these are factors of 3 too, we get 21/30. Doing it yet again since 21 and 30 are factors of 3, we get 7/10 as our answer

Answer:
416666666/100000000
Step-by-step explanation:
To write 4.16666666 as a fraction you have to write 4.16666666 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
Because the coefficient of x^2 is -1, we know that a will be -1. Knowing that the coefficient of x is -4, we can calculate that p=2. Thus, we have -1(x+2)^2+q is our equation. This is equal to -x^2-4x-4+q. As the constant term must be 2, we can then see that q is 6.
As such, we have -1(x+2)^2+6=0 as our factorization.
To solve this equation, we can use the quadratic formula. Plugging in values, we have:

which is equal to: (when the fraction is simplified)
They are both correct becuase lets say it was a shirt that was $30 and it was 30% off. For Jasani it would be 30 * 0.7 which equals $9 then you would subtract this 30 - 9 = 21. For Hanna it would be 30 - 0.3(30) which equals $21. So in the end they are both correct!
