Question

One glass of milk provides 305mg of calcium. Maggie drinks one glass of milk every morning. How many grams of calcium does Maggie get from her milk in 14 days?

Answer 1

she drinks 4.27 grams on calcium in 14 days at one glass of milk containing 14 mg per day

Answer 2

4.27grams

Explanation:

The initial information we have can be represented in one table:

Glasses of milk Calcium

1 ⇒ 305mg

and we are told that Maggie drinks one gass of milk every morning.

that means that in 14 days she has drunk 14 glasses of milk, I will represent the amount of calcium in 14 glasses of milk by x :

Glasses of milk Calcium

1 ⇒ 305mg

14 ⇒ x

We solve this problem by multiplying the cross quantities in the table (305 and 14):

x= (305mg)(14)

x = 4270mg

but we need the answer in grams not in miligrams.

So we make the conversion, since 100mg = 1g

4270mg = 4.27g

The answer is 4.27grams
