This is confusing

To solve this problem, we can set up a proportion using the given information.

Let's start by setting up the proportion:

(8 fluid ounces) / (270.0 milligrams of calcium) = (x fluid ounces) / (72.5 milligrams of calcium)

Now, we can cross-multiply:

(8 fluid ounces) * (72.5 milligrams of calcium) = (270.0 milligrams of calcium) * (x fluid ounces)

Now, we can solve for x by dividing both sides of the equation:

(8 fluid ounces * 72.5 milligrams of calcium) / (270.0 milligrams of calcium) = x fluid ounces

Evaluating the expression, we get:

(580 milligrams) / (270 milligrams) ≈ 2.148...

Round to the nearest tenth, we get x ≈ 2.1 fluid ounces.

Therefore, approximately 2.1 fluid ounces of milk provide 72.5 milligrams of calcium. So, the answer is 2.1 fluid ounces.
