Tyler spends a winter day recording the temperature once every three hours for science class. At 9 am, the temperature was -1.8°F. Between 9am and noon, the temperature rose 5°F. Between noon and 3pm, the temperature dropped 18.1°F. Between 3pm and 6pm, the temperature decreased by 9.9°F. What was the temperature at 6pm?

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
