6 the six members of the arnold family calculate the familys daily water use to be 38 gallons. which equation best shows the average amount of water each person uses daily?
a 6÷38 = 3/19
b 38÷6 = 6 1/3
c 6/38 = 0.15
d 38/6 = 6.03

Explanation:

Step1: Solve problem 1

To find the decimal equivalent of $\frac{3}{10}$, we divide 3 by 10. So, $3\div10 = 0.3$. The answer is C.

Step2: Solve problem 2

Alejandro has 8 cans of soda to share among 16 friends. The amount of soda each friend will receive is given by the division operation $8\div16$ or the fraction $\frac{8}{16}$. So the correct answers are $8\div16$ and $\frac{8}{16}$.

Step3: Solve problem 3

Calculate $\frac{7}{20}=7\div20 = 0.35$. The statistic in the table that matches 0.35 is On - Base. So the answer is C.

Step4: Solve problem 4

A 50 - minute block of computer time is shared equally among 3 students. The amount of time each student gets is $50\div3=\frac{50}{3}=16.\overline{6}$. So the answer is D.

Step5: Solve problem 5

Montrel practices $\frac{3}{2}$ as many days as last year. $\frac{3}{2}=1.5$, $3\div2 = 1.5$, $1\frac{1}{2}=1.5$. But $2\div3=\frac{2}{3}\approx0.67$. So the answer is A.

Step6: Solve problem 6

The Arnold family uses 38 gallons of water in total and there are 6 members. The average amount of water each person uses daily is $38\div6=\frac{38}{6}=6\frac{1}{3}$. So the answer is B.

Answer:

1. C
2. $8\div16$, $\frac{8}{16}$
3. C
4. D
5. A
6. B
