Answer 2

Here we have to find 2.5 % of which number gives 2liter 450 ml

We will first convert the entire number into ml

2 liter 450 ml = 2450 ml

Let the number be 'x' ml

This can be mathematically represented as

2.5% × x = 2450 ml

$\frac{2.5}{100} \times x= 2450$

Now, we will rearrange the equation

$2.5x = 2450\times100\\2.5x= 245000\\x=\frac{245000}{2.5} \\x=98000$

So, 2.5 % of 98000 ml / 98 liter will give 2450 ml / 2 litre 450 ml
