Answer: 24.8
Explanation: If Henry is halving a number, that means he's dividing it by 2, getting two halves. You would get the original number by undoing that division, or multiplying the product by 2.
2 x 12.4 = 24.8
Well the way that I rounded this was up so I rounded 9.3-10 and 35.8-40 then I took 40*10=400 (mental math (approximation)) and because 400<3,329.4 this answer is highly unreasonable.
