## anonymous one year ago The Atlantic Ocean region contains approximately 2 ×10^16 gallons of water. Lake Ontario has approximately 8,000,000,000 gallons of water. How many Lake Ontarios would it take to fill the Atlantic Ocean region in terms of gallons of water?

$\frac{ 2 \times 10^{16} }{ 8 \times 10^9 }$

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?

oh I see thank you

16

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

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