20 L of water was removed from a tank that was 1/3 full,the tank was 1/9 full.the capacity of tank in liters?

Answer 1

Initially the tank is 3/9 full. After transfering it is left with 1/9 of water. So 2/9 of the water in the tank is 20L.

2 units = 20L
1 unit = 10L
9 units = 90L

The capacity of the tank is 90L

=)

Answer 2

1/3 = 3/9

20 liters = 3/9-1/9 = 2/9

so you can say that 2/9 of the volume of the tank = 20 L

(2/9)V =20

and V = 90L

Answer 3

1/3 *x -20 = 1/9*x==> 2/9*x = 20 III x=90 liters is the capacity

Answer 4

so which you calculated you are able to desire to eliminate 32 cups from a ten gallon tank. purely use a ratio. The 25 gallon tank is two.5 circumstances greater beneficial (25/10), so which you eliminate 2.5*32, which = 80. 20% is a ratio, 20 areas of one hundred areas, or reducing words, a million section out of 5. proportion is purely a ratio of a few style to a handy around style, one hundred. you need to replace 25 on your pattern calculation and verify the respond of 80 the two besides, yet i admire the two.5 circumstances ratio thought greater proper. in spite of if, why use cups in any respect? Why no longer use a gallon plastic bottle? 20% skill eliminating a million of each and every 5 gallons, or 5 gallons finished. utilising a gallon bottle looks much less complicated the 1st time after which make a mark, after which later, use a siphon to empty to the mark and replenish. The siphon is via a protracted way the finest thank you to empty water from an aquarium. purely be careful to no longer suck up the fish!!! whilst utilising a siphon, use a tube with a funnel in the tank with mesh netting over the massive end of the funnel, that may not enable a fish to get caught sucked onto the top of the tube.

Answer 5

x/3 - x/9 = 20 L
(2/9)x = 20 L
x = 20*9/2 = 90 L

Answer 6

3/9 - 1/9 = 2/9

2/9 = 20L


9/2 = 4.5

4.5 x 20L = oops

Answer 7

suppose the vol. of tank=V
then:
V/3 -20=V/9

there fore after solving,
V=20*9/2
=90L
