Answer 1

0.2 part of the tank is filled.

• The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units. Always write the items that need to be computed on the right side and the things that are known on the left side to simplify things.
• In the unitary method, the value of a unit quantity is determined before the values of other units are determined. Direct variation and inverse variation are the two different sorts of variations it has.
• When there is a direct variation, an increase or decrease in one quantity will result in an equivalent rise or fall in the other. For instance, a rise in the quantity of commodities will result in higher costs.

Here, according to the given information, it is given that,

In 25 hours a full cistern is filled.

In 1 hour, $\frac{1}{25}$th of the cistern is filled.

In 5 hours, $\frac{1}{25} .5=\frac{1}{5} =0.2$ portion of the cistern is filled.

Hence, 0.2 part of the tank is filled.

Answer 2

Answer:

$\frac{1}{5}$  part of the tank will fill in 5 hours means it will be 0.2 portions of the tank would be filled.

Step-by-step explanation:

The question is given that a tank is filled fully in 25 hours and we have to Calculate how much tank would be filled in 5 hours

and as per the solution the if  1/25 part of the tank is filled in a 1hour so 1/25 multiplied by 5 and it will give the answer 1/5 or 0.2

so this much part would be filled in particular 5 hours.

as per the question

it is given that,

a pipe can fill a  cistern in 25 hours.

so, calculating the part filled in 5hrs

as we know,

In 25 hours the full cistern is filled

so, if in 1hr  $\frac{1}{25} th$ of the cistern is filled and in 5 hours it will be $\frac{1}{25} \times5$ that is $\frac{1}{5}$ or 0.2 so, the particular portion will be filled in 5 hours.

Hence, $\frac{1}{5}$  part of the tank will fill in 5 hours means it will be 0.2 portions of the tank would be filled.
