Ateacher let her students grade their math quizzes jon wrote 13 of 18 jim wrote .7 joe reduce his to 5/6 who had the higher grade?

How had the higher grade

Step-by-step explanation:

13/18 is equivalent to .72 wihuc is 72%, .7 is the same as 70% and lastly 5/6 = .83 = 83%.

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.
