Question

A multivitamin tablet contains 14.5mg of calcium. How much calcium does a bottle of 50 tablets contain? Write your answer in grams.

Answer 1

.725 grams
14.5 times 50 is 725. 725 divided by 1000 (because there are 1000 milligrams in a gram) which equals .725

Answer 2

The correct answer is 725mg of calcium.

Explanation:

To solve this problem, you can to use the rule of three.

• 1 tablet → 14.5 mg.
• 50 tablets → x mg.

Now, you have to multiply 50 tablets by 14.5 mg, then divide by 1 tablet:

`x = (50 tb * 14.5mg)/(1 tb) = 725 mg` // tb divided by tb is 1

`x = 725 mg`
