Okay so apparently there are some aliens on the world and be have to stop them by using 3 proportion questions on them, so here are my question and answers...
1. Question 20.
A breakfast cereal contains corn, wheat,
and rice in the ratio of 3 to 4 to 2. If a
box of cereal contains 225 g of corn, how
much rice does it contain?
It contained 150 g of rice.
The reason why I multiplied by 74 is because 3 times 75 gives you the answer 225 . Whatever you do to one side you have to do to the other.
2. Question 5.
What is the unit rate in each?
a. Two pens cost 94¢.
b. Four blocks stacked one on top of
the other are 24 cm high.
Sorry I don't have one for page 69. I went up to 24 but I didn't get the answer(s).
I've saved our planet from some of the aliens (:
