This written out is:

2/5 + 4/3
------------
     3/5

Roughly, now first we need to change the denominators to all match up in order to properly solve this problem.

Both 5 and 3 go into 15, 5 goes into 15 3 times and 3 goes into 15 5 times. With that said, multiply the individual numerators by 5 and 3.

2/5 -> 2*3/15 -> 6/15
4/3 -> 4*5/15 -> 20/15
3/5 -> 3*3/15 -> 9/15

With this, we then add the top numerator of the overall problem:

26/15
------- | With this we now cross-multiply.
 9/15

26/15 * 15/9 = 390/135 | Now to simplify this.

135 goes into 390 twice, as 270. Subtract 390 by 270, leaving us with 120.

Meaning: 2 120/135 is the answer, but now to simplify. Divide 120 and 135 by 5 to lessen this.

24/27 | Divide this by 3 to get your most simplified answer.
8/9 | Leaving us with the answer of:

2 8/9

I hope this helps, have a great rest of your day! ^ ^

if an office of 36 typist uses 12 dozen envelopes per day how many dozen envelope would an office of 125 typists of use?
Pani-rosa [81]
Assuming the envelope consumption is proportional to the number of typists, you have ...
  (12 dz)/36 = x/125
  125*(12 dz)/36 = x = 41 2/3

An office of 125 typists would use 41 2/3 dozen envelopes per day.
