Any number divided by zero is undefined. so you would want zero in the bottom or denominator. if you sub 1 in for x you would get zero in the denominator. so 1
You would have the fraction
11 out of 16 (which is 11/16)
And since the / symbol also means division
You would divide 11 by 16 to get
0.6875
So about 69% correct
4.19 is your answer. 4 being your whole number and your 19 is in the hundredths place since it goes, tens, hundredths, thousandths.
