Answer:
The ratio of the areas of the smaller rectangle to the larger rectangle is 
Step-by-step explanation:
we know that
if two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z-----> the scale factor
x-----> the area of the smaller rectangle
y----> the area of the larger rectangle
so

substitute the values

simplify

That means, the area of the larger rectangle is 9 times the area of the smaller rectangle
------> the scale factor
That means, the dimensions of the larger rectangle is 3 times the dimensions of the smaller rectangle
Amount of chemical A mixed in medicine = 9.357 g
Amount of chemical B mixed in medicine = 12.082 g
Amount of chemical C mixed in medicine = 7.502 g
We have to determine the total amount of medicine he prepared in grams.
Total amount of medicine
= 9.357 + 12.082 + 7.502
= 28.941 grams
So, he prepared 28.941 grams of medicine.
Now, we have to round each chemical to the nearest tenth.
Amount of chemical A mixed in medicine = 9.357 g
Rounding to nearest tenth = 9.4 grams
Amount of chemical B mixed in medicine = 12.082 g
Rounding to nearest tenth = 12.1 grams
Amount of chemical C mixed in medicine = 7.502 g
Rounding to nearest tenth = 7.5 grams
