<h2><u>Solution</u> :-</h2>
Height of Eric = 6 + 1/6 feet
= 37/6 feet
Height of his brother = 5 + 3/4 feet
= 23/4 feet
Difference between their height :
= 37/6 - 23/4
= (74 - 69)/12
= 5/12
<u>Hence</u>,
Eric is 5/12 feet taller than his brother.
You need to be clearer on what the "roots" are, I haven't learned that term ever, but I think I know what you mean...
7 minutes per mile so around 2.5 miles
7/11 = 0.63 with a line over the 63 because it repeats = 63.6%
