least to greatest = 0.0128%, 50%, 55%, 68%
descending
4% = 0.04 So in order of smallest to greatest we have: 4%, 0.34, 0.4, 2.3 & 3.4
They are: -22, -6 and 11
The answer is 15.03, 15.2, 15.25 least to greastest.
The easiest way it to convert them all to decimals. Carry out the repeating decimals to an equal number of places. Then it is easy to put them in order.
least to greatest: 0.03%, 21%, 78%
5% is least, then a half and then 0.55
7%, 0.65, 67%, 23, 68
5%, one half, 0.55
0.59 is the smallest. In order from Greatest to Least: 13/20 63% 60% 0.597 0.59
72.5% All you need to do is line them up in order from least to greatest. Then you cross one out from the left then from the right. Next you add up both the numbers and divide by 2.
-a 6/8 is a 75% -a 7/8 is an 87% So in order to get at least an 80%, you must score at least a 7
