Question

resuelve las operaciones simplifica si es posibe por favor rapido respondan lo necesito ya plis porfis gachas

A.3/8 +5/8 D 2 1/5+ 5 1/3 G. 3- 3/5

B 1+ 2/3 E. 1/5+ 1/3 H. 5/8 - 1/5

C. 5 2/3+1/4 F. 2/5 +11/5 I. 5/3 -1

Answer 1

A.3/8 +5/8 
directa:
= 8/8 = 1

B 1 + 2/3 
= 3/3 + 2/3
= 5/3

C. 5 2/3+1/4
= 5 + 2/3 + 1/4
= 15/3 + 2/3 + 1/4
= 17/3 + 1/4
= 68/12 + 3/12
= 71/12

D 2 1/5+ 5 1/3
= 2 + 1/5 + 5 + 1/3
el mcm de 5 y 3 es 15, llevamos las fracciones a 15avos
= 30/15 + 3/15 + 75/15 + 5/15
= 113/15

 E. 1/5+ 1/3
= 3/15 + 5/15
= 8/15

F. 2/5 +11/5
directa
= 13/5

G. 3 - 3/5 
= 15/5 - 3/5
= 12/5

H. 5/8 - 1/5
el mcm de 8 y 5 es 40
= 25/40 - 8/40
= 17/40

I. 5/3 -1
= 5/3 - 3/3
= 2/3

Answer 2

a)3/8+5/8=8/8=1
b)1+2/3=3/3+2/3=5/3
c)5 2/3+1/4=17/3+1/4=68/12+3/12=71/12
d)2 1/5+5 1/3=11/5+16/3=33/15+80/15=113/15
e)1/5+1/3=3/15+5/15=8/15
f)2/5+11/5=13/5
g)3-3/5=15/5-3/5=12/5
h)5/8-1/5=25/40-8/40=17/40
i)5/3-1=5/3-3/3=2/3
