What is the sum of 5 different fractional units of 1,

What is the sum of 5 different fractional units of 1,

1=1/2+1/6+1/12+1/20 +1/5
1=(1/1-1/2)+(1/2-1/3)+(1/3-1/4)+(1/4-1/5)+1/5=1/(1*2)+1/(2*3)+1/(3*4)+1/(4*5)+1/5

If a fraction is added to one of its fractional units, the sum is 1, and if it is subtracted from one of its fractional units, the difference is seven eighths. What is the fraction?
The faster the better!

15 out of 16

How much is a fraction that is added, subtracted, divided, and the sum, difference, and quotient of itself add up to four-thirds

Add it to itself, and it's twice that
Subtraction = 0
Division = 1
So the score is (4 / 3-1) △ 2 = 1 / 6
That's one in six
Have a good time

If a fraction is added, subtracted and divided with itself, the sum, difference and quotient will be added up to 4 / 3

Let the score be B / A
The meaning of the title is: (B / A + B / a) + (B / a - B / a) + (B / a) / (B / a) = 2 * B / A + 0 + 1
= 2*b/a + 1
= 4/3
After calculation, B / a = 1 / 6
