Question

A multivitamin tablet contains 14.5mg of calcium. How much calcium does a bottle of 20 tablets contain?Write your answer in grams.

Answer 1

Answer: 0.29 grams

Since one tablet contains 14.5mg of calcium, we can find how much calcium does a bottle of 20 tablets contains by multiplying the number of tablets by the amount of calcium.

`\frac{14.5\text{ mg of calcium}}{1\text{ tablet}}*20\text{ tablets}=290\text{ mg of calcium}`

Now, since we are asked to answer in grams, we will convert mg to g. To do this, we will divide the value by 1000

`\frac{290\text{ mg }*1\text{ g}}{1000\text{ mg}}=0.29\text{ g}`

Therefore, a bottle of 20 tablets contains 0.29 grams
