    Can I have help with this question? I'm quite stuck lol

    The Heron Sea has a volume of 1.4 x 10 (to the power of 14) litres, of which 12% is salt.
    The Cobalt Sea has a volume of 8.5 x 10(to the power of 12) litres, of which 8% is salt.

    What is the percentage decrease in the volume of salt from the Heron Sea to the Cobalt Sea? Give your answer to 2 decimal places.

    You can start by finding the amount of volume of salt it the Heron Sea, and then find the volume of salt in the Cobalt sea.

    From these two volumes you should be able to find the percentage decrease in the volume of salt.
