Remember PEMDAS or GEMDAS.
For (1/2 - 1/3) you have to find a common factor of 2 and 3, the denominators, which would be 6. So 1/2= 1x3 and 2x3 giving you 3/6. Then for 1/3 it would be 1x2 and 3x2 which equals 2/6, now you subtract the nominators: 3-2=1 the answer is 1/6
Then we divide 1/5 by 1/6 and we’ll use KFC for that: Keep the 1/5 change the division sign to multiplication sign and change 1/6 to its reciprocal 6/1
Now we have 1/5x6/1=6/5=1 1/5
6/5+1/4 we find common denominators: 6x4 and 5x4 is 24/20 + 1x5 and 4x5 which is 5/20
Now we have 24/20+5/20=29/20 simplified it is 1 1/20
A)1 1/20
