Well, first, let's figure out how many ounces there are in (3 and 3/8) pounds.
Then we'll be able to compare it to the 54 ounces on the other side.
Before you can make any progress at all, you need to know how many ounces there are in one pound . . . . . there are 16 of them.
3 pounds = 3 x 16 = 48 ounces
3/8 of a pound = (3/8 x 16) = 6 ounces
Total (3 and 3/8) pounds = (48 + 6) ounces = 54 ounces .
Guess what ! The inequality statement isn't an inequality at all.
It's an equality.
3 and 3/8 pounds = 54 ounces
54 ounces = 54 ounces
