Answer:

$\frac{63}{32}oz$ or 1.96875oz

Step-by-step explanation:

You can solve this problem by setting up a ratio. The first step is to convert the dosage into decimal form. 3/4oz=0.75oz. Now, you know that for a 24 pound child, you need 0.75oz of medicine. 24:0.75=63:x, which can be turned into the fractions $\frac{24}{0.75}=\frac{63}{x}$ . Multiplying both sides by x and dividing both sides by $\frac{24}{0.75}$ , you get x=1.96875, or $\frac{63}{32}oz$ . Hope this helps!
