When can we compare decimals in the real world?
Any time we compare decimals, except in out dreams/nightmares! We cannot leave the real world purely for the purpose of comparing decimals and return to the real word when we have done that!
How do you do greatest to least in fractions and decimals?
To compare decimals: look at the highest-order digit and compare. If it is the same, look at the next digit, and so forth. Thus, 23.5 is greater than 11.4 (because the tens digit is greater), 123.88 is greater than 25.82 (because the second number has no hundreds digit, so you can take it to be zero), 115.28 is greater than 113.99 (the first two digits are equal, so you compare the third digit). To compare fractions: use a calculator to convert to decimals, then compare. Alternately, you can convert to a common denominator, then compare the numerators.
