2 answers:
Answer: 1 2/7
Step-by-step explanation:
Set up a proportion:
1/7 L of water - 1/9 of the aquarium
x L of water - 1 aquarium (the whole aquarium)
![\frac{\frac{1}{7}}{\frac{1}{9}}=\frac{x}{1} \\ \\ \frac{1}{7} \times 9=x \\ \\ \frac{9}{7}=x \\ \\ x=1 \frac{2}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B1%7D%7B7%7D%7D%7B%5Cfrac%7B1%7D%7B9%7D%7D%3D%5Cfrac%7Bx%7D%7B1%7D%20%5C%5C%20%5C%5C%0A%5Cfrac%7B1%7D%7B7%7D%20%5Ctimes%209%3Dx%20%5C%5C%20%5C%5C%0A%5Cfrac%7B9%7D%7B7%7D%3Dx%20%5C%5C%20%5C%5C%0Ax%3D1%20%5Cfrac%7B2%7D%7B7%7D)
