If a 150 pound woman would receive 24 grams of a certain medicine. how many grams should a 120 pound woman receive?

With a problem like this, set up a proportion (like when making lemonade from a mix).

is our proportion.

We fill in the the two weights and the 24 grams of medicine in the proportion and solve for the fourth piece not there.

We shorten medicine to M and we solve for M by cross multiplying.

The woman should get 19.2 grams of medicine.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
