    We transform the number 3 into a fraction 21/7 and then we substract it from the fraction on the right to get the value of thw variable f

    -the answer is B f = 11 and 2/7

    - you could also just put the solutions from A, B, C and D into F and comapre left side to the right side (when they're equal you have the right f)
