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.

b) 1/3 * 1/5

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
