Answer:

Aaron travelled about 9 feet underwater

Step-by-step explanation:

We need to work with the information we are given in the question.

there are two stages of Aaron's travel. the first distance was in the air, and the second distance was in the water.

We are given both the total distance travelled and the distance travelled in the air.

To get the distance travelled in water, we subtract the distance travelled in the air from the total distance.

This will be 52 feet - 43 feet = 9 feet

Hence Aaron travelled about 9 feet underwater

Fter completing the fraction division 7/3 : 2/9 , Bai used the multiplication below to check his work.
Vitek1552 [10]
First off all, let's find 
\dfrac{7}{3} : \dfrac{2}{9} = \dfrac{7}{3} \cdot  \dfrac{9}{2}= \dfrac{63}{6} = \dfrac{21}{2}.

This shows that Bai found the correct quotient.

If a:b=c, then a=c\cdot b. Using this rule, you have to check that \dfrac{7}{3} is equal to product  \dfrac{21}{2} \cdot  \dfrac{2}{9}. 

Thus, Bai checked his work using multiplication correctly.

Answer: Correct choice is A.
