Answer 1

Answer:

35437.5 Liter

Step-by-step explanation:

A person needs water for 1 day = 4500 ml

water need for 275 people for 45 days =

45000*275*45= 35,437,500ml

ml convert into liter

35437500/1000 = 35,437.5 liter

Answer 2

Question :

A person needs 4500 ml of water per day for drinking.Find the amount of water needed for 275 people for 45 days.

Answer : 55687.5 litre.

Solution:

$\longrightarrow$ Consumption of water by a person in one day = 4500ml.

$\longrightarrow$ We know that, 1 litre = 1000ml

$\longrightarrow$ So,consumption of water by a person in one day = 4500/1000 = 4.5 ml.

$\longrightarrow$ Consumption of water by 275 such people in one day = 4.5 × 275 = 1237.5 litre.

$\longrightarrow$ Consumption of water by 275 such people in 45 days = 1237.5 × 45 = 55687.5 litre.

Additional information:

We should convert the units in order to make them easy to simplify.

The following chart is suitable for mass and length units.

$\longrightarrow$ Kilo gram/litre/metre.

$\longrightarrow$ Hacto gram/litre/metre.

$\longrightarrow$ Deca gram/litre/metre.

$\longrightarrow$ Gram/Litre/Metre.

$\longrightarrow$ Deci gram/litre/metre.

$\longrightarrow$ Centi gram/litre/metre.

$\longrightarrow$ Mili gram/litre/metre.

From the above chart, if we want to change the units from upper to lower unit then we should multiply by 10 each time coming downwards.

From the above chart, if we want to change the units from lower to upper unit then we should divide by 10 each time going upward.
