PLZ HELP!
6 oz./202.5mg * 52.5mg = 1.56 oz.
To find out how many fluid ounces of milk are required to provide 52.5 milligrams of calcium, we can set up a proportion using the given information.
We know that 6 fluid ounces of milk provides 202.5 milligrams of calcium. Let's call the unknown number of fluid ounces of milk "x".
The proportion can be set up as follows:
6 fluid ounces / 202.5 milligrams = x fluid ounces / 52.5 milligrams
To find the value of "x," we can cross-multiply and then solve for "x".
6 * 52.5 = 202.5 * x
315 = 202.5x
Divide both sides of the equation by 202.5:
315 / 202.5 = x
1.5556 = x
Rounding to the nearest tenth, we can say that approximately 1.6 fluid ounces of milk are required to provide 52.5 milligrams of calcium.
