Answer 1

Respuesta:

a). 2/5 + 3/20 = 11/20

2/5 + 3/20

= 8+3/20

= 11/20

b). 1 1/4 + 1 2/8 = 5/2

1 1/4 + 1 2/8

= (1+1) + (1/4 + 2/8)

= 2 + (1/4 + 2/8)

= 2 + 1/2

= 2 1/2

= 5/2

c). 1 3/5 + 4/15 = 28/15

1 3/5 + 4/15

= 8/5 + 4/15

= 28/15

d). 2 1/2 + 2/6 = 17/6

2 1/2 + 2/6

= 5/2 + 2/6

= 17/6

e). 3/8 + 2/24 = 11/24

= 9+2/24

= 11/24
