gallons of water. How many Lake Ontarios would it take to fill the Atlantic Ocean region in terms of gallons of water?

Answer 1

\[\frac{ 2 \times 10^{16} }{ 8 \times 10^9 }\]

Answer 2

notice that i made this into a division expression. it's basically asking how many more times is the atlantic ocean region contains gallons of water compared to lake ontario. do you understand?

Answer 3

oh I see thank you

Answer 4

do you know the answer?

Answer 5

16

Answer 6

\[\frac{ 2 \times 10^{16} }{ 8 \times 10^9 } = \frac{ 2 }{ 8 } \times \frac{ 10^{16} }{ 10^9 } = \frac{ 1 }{ 4 } \times 10^7 = 0.25 \times 10^-1 \times 10^7 = 2.5 \times 10^6\]

Answer 7

\[0.25 \times 10^{-1} \times 10^7 = 2.5 \times 10^6\]
