Answer 1

Answer:

2.5 litres water is left after the picnic.

Step-by-step explanation:

Given :

Water carried = 25 litres

Water consumed = 9/10

To find :

Water left

Solution :

First, find the 9/10 part of the total water

➡ 9/10 of 25

➡ 9/10 × 25

➡ 9/2 × 5

➡ 4.5 × 5

➡ 22.5

22.5 litres were consumed in the picnic.

$\rule{300}{1.5}$

Water left -

Total Water - Water consumed

➡ 25 - 22.5

➡ 2.5

Water left = 2.5 litres

$\therefore$ 2.5 litres water is left after the picnic.

Answer 2

Answer:-

Water left = 2.5 litres

Further Explanation

According to the given question

25 litres is the water carried.

$\frac{9}{10} \: is \: the \: \: Water \: consumed$

According to the question we need to find the amout of water left

So,

$= > ( \frac{9}{10} = 25) \\ </p><p> = > ( \frac{9}{10} × 25 )\\ </p><p> = > (\frac{9}{2} × 5) \\ </p><p> = >( 4.5 × 5) \\ </p><p> = > ( 22.5)$

So,22.5 of water is left in the picnic

Now let us subtract the total number od Water with the amount of water consumed in the picnic.

$= > (25 - 22.5) \\ </p><p> = > (2.5)$

So,subtracting we get 2.5 litres

Hence, water left after the picnic = 2.5 litres
