Answer: 10/3 liters

Explanation:

To find out how much water is necessary to water all the plants in the house, you can set up a proportion based on the given information.

Let "W" represent the amount of water necessary to water all the plants in the house (in liters).

We are given that 4/3 liters of water are enough to water 2/5 of the plants. So, you can set up a proportion:

(4/3 liters) / (2/5 of the plants) = W / (all the plants)

Now, let's set up the proportion:

(4/3) / (2/5) = W / 1

To solve for "W," multiply both sides of the equation by 1 (which doesn't change anything):

(4/3) / (2/5) = W

Now, to simplify this, you can multiply the left side by the reciprocal of the denominator:

(4/3) * (5/2) = W

Now, multiply the fractions:

(4 * 5) / (3 * 2) = W

(20/6) = W

Now, simplify the fraction:

(10/3) = W

So, it would take 10/3 liters of water to water all the plants in the house.

You can also express this as a multiplication equation and a division equation:

Multiplication Equation: 4/3 liters * (5/2) = 10/3 liters

Division Equation: (4/3 liters) ÷ (2/5) = 10/3 liters
