i'm no longer able to respond to that, because of the fact for that fraction, i don't be attentive to if the numerator is 5, (4+5), (2*4+5). comparable with the denominator. regardless of if, if i assume which you propose: 2 x 4 + (5 / 2) - 3 x 4 + 3 = then stick to the order of operations, PEMDAS. That stands for Parentheses, Exponents, Multiplication, branch, Addition Subtraction. Multiplication and branch are achieved on the comparable time yet from left to remarkable, as are addition and subtraction. So first, you are able to no longer do something with what's in parentheses, and there are actually not any exponents, so initiate with multiplication and branch: (2*4) + (5/2) -(3*4) +3 = 8 + (5/2) -12 +3 Now, upload or subtract from left to remarkable: (8 5/2) -9 convert to incorrect fractions with a denominator of two: 21/2 - 18/2=3/2 So the respond is 3/2.
