Which of the following is closest to the difference between sum of all proper fractions (fractions less than 1) in the form 1/x , where x is a positive digit, and the product of all proper fractions in the form y/(y+1), where y is a positive digit?	Choose the correct choice from the following answers:
A) 2.82
B) 2.72
C) 1.82
D) 1.72
E) 0.82
First term = 1/2 +1/3 +1/4 +1/5 +1/6 +1/7 +1/8 + 1/9   Second term = 1/2 * 2/3 * 3/4 * 4/5 * 5/6 * 6/7 * 7/8 * 8/9 * 9/10 = 1/10   First term - Second term = 1/2 + 1/3 + 1/4 + 1/5 + 1/6 + 1/7 +1/8 + 1/9 - 1/10   Now rearrange the above equation for simplification:   = (1/2 + 1/5 - 1/10) +( 1/3 + 1/6 + 1/9) + (1/4 + +1/8) +1/7   = 6/10 + 11/18 + 3/8 +1/7   6/10 , 11/18, 3/8 are approximately equal to 0.5   =0.5+0.5+0.5+0.14=
