Answer 2

Respuesta:

1. 20/21

2. 19/40

3. 271/45

4. 13/8

5. 61/35

Explicación paso a paso:

1 .  4 /6 + 2/7 = 28+12 /42 = 20/21

2.  3/5 – 1/8  =  24 -5 /40  = 19/40

3.  2.4/5 + 3.2/9 = 14/5 +29/9 = (126+145)/45 =271/45

4.  3.2/4 – 1.7/8 = 14/4 – 15/8 = (112 – 60 )/32 = 52/32 = 13/8

5.  8/7 + 6/10  = (80 + 42)/70 =122/70 = 61/35
