3 tablets
Work Step by Step
First, convert the daily recommended calcium intake from grams to milligrams
$$1.5 g \times \frac{1000 mg}{1 g}=1500 mg$$
Knowing that each tablet contains 500 mg of calcium, we can now calculate for the number of tablets that the woman should intake
$$1500 mg \times \frac{1 tablet}{500 mg}=3 tablets$$
