Ms. Salazar's rice mixture consists of seven parts of white rice to three parts ofwild rice. If she makes 30 cups of the mixture, how many cups of white rice will she use? How many cups of wild rice will she use?
7 white rice: 3 wild rice for 10 total
then by multiplying all by 3, it's now
7*3 cups of white rice: 3*3 cups of wild wice for 10*3 total cups.
Which ends up to be 21 cup white rice and 9 cup wild rice
