Caroline is doing a traffic survey. on the first day, the ratio of
cars with passengers to cars with only a driver was 13: 7. on
the second day, the ratio was 8: 5. on which day was the
percent of cars with passengers greater? how do you know?

1st day = 13/20×100 = 65%

2nd day = 8/13×100=61.53%

1st day answer

step-by-step explanation:

a rhombus is a parallelogram enjoying his symmetry.

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.
