Answer:

1. 5/7

2. 6/11

3. 1 1/4

4. 1

Step-by-step explanation:

1. 3/4+2/3= 3+2= 5 ; 4+3=7 = 5/7

2. 5/8+1/3= 5+1= 6 ; 8+3= 11 =6/11

3. 6/9-1/5= 6-1= 5; 9-5=4 = 5/4 (Note: since the numerator is much bigger than the denominator we only have to change it into a mixed fraction)

5/4 = 1 1/4

4. 4/5-1/2= 4-1= 3; 5-2= 3 =3/3 (Note: since both numerator and denominator is a same number the most simplest thing we could do is divide it in order to become a whole number)

3/3= 1
