Answer 1

As per the details provided in the above question we have,

In the provided details we have,

The given data is oil used for first day is 72L 675ml.

second day oil used is 65L 287 ml.

We have to find the day in which more oil is required for cooking.

Here we have to use the formula of conversion from kilometre to millilitre.

Thus, converting 72L 675ml

1 liter = 1000ml

$72 \times 1000 = 72000$

So, total oil used for first day is, =72000+675=72675ml

Therefore, converting 65L 287ml

$65 \times 1000 = 65000$

The total oil used for second day is, =65000+287=65287ml

Comparing both first day use and second day we get 72675ml is greater than 65287ml.

Difference is = 72675-65287=7388ml

Hence first day use of cooking oil is more and the difference was 7388ml.
