    4.27grams

    Step-by-step 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
