It's subtraction or multiplacation
90 or 100 something like that.
We know that 1 lb = 16 oz
So lets convert the 20 lb to oz and then compare the two quantities in consistent units.
If 1 lb = 16 oz then 20 lb are equal to 20*16 oz, that is
20 lb = 20*16 oz = 320 oz
therefore,
320 oz are greater than 272 oz, or,
20 lb are greater that 272 oz
We would need to know how many students are in the class to properly answer the question.
Eagles, Wolves, Mustangs because 95%=.95 and then 9/10=.9 and then .89 is less than both of those.
