Answer 1

Boa noite Samuel

a) 1/8 + 1/4 = 1/8 + 2/8 = 3/8 

b) 3/8 + 9/16 = 6/16 + 9/16 = 15/16 

c) 11/32 + 5/8 = 11/32 + 20/32 = 31/32

d) 7/16 - 5/16 = 2/16 = 1/8 

e) 1/2 - 3/8 = 4/8 - 3/8 = 1/8 

f) 17/32 - 15/32 = 2/32 = 1/16 

g) 3/4 + 1/2 - 3/8 = 6/8 + 4/8 - 3/8 = 7/8 

h) 1/4 + 1/8 + 9/16 = 4/16 + 2/16 + 9/16 = 15/16 

i) 23/32 - 1/64 = 46/64 - 1/64 = 45/64 

j) 11/30 + 14/15 - 1/2 = 11/30 + 28/30 - 15/30 = 24/30 = 4/5 

h) 29/64 + 1/2 = 29/64 + 32/64 = 61/64
