For those getting confused about the denominators, they are that way after taking LCM of the denominators prior to the calculation, eg. LCM(12, 15) = 60 and then since 12 * 5 = 60, 15 * 4 = 60 we see, (5 + 4)/60.

As for those who don't understand subtraction with 1, remember fractions range from 0 to 1, 0 being lowest and 1 being maximum. So if you subtract any fraction with 1, you get the remaining fraction. That's why if B worked for 23 days = 23/40 then the days B didn't work alone/remaining days = 1 - 23/40 = 17/40.

for those who is confused about question no 4:
(X/45 + (X+23)/40) = 1unit of work
X = 9 days!
A worked X days,
B worked X days and 23 more days!

for people getting confused in Q.1 why reciprocal so, Work = (combined Rate of work) x Time Taken, here the Work is complete completion of work so (W=1) i.e. W = R x T => 1 = R x T , hence, T = 1/ R. (Time taken = 1/Combined Rate)

[godrutikyt]
