Answer 2

The first one is either a typo or a trick, since no number of cm^2 make a litre. Was ir cm^3?

There are 1000 cm^3 in a L.

By "simplify", I presume the question means convert to one unit - either pounds or ouncez. There are 16 oz in a lb, so one pssible answer is
(10 * 16) + 28 oz.

But since 28 is more than 16, it's possible the questioner wants you to notice that, and say that 28 oz = 16 oz + 12 oz = 1lb + 12oz, and add the extra pound and reduce the oz accordingly.

Answer 3
