Question

Efetue as subtracoes a)7/9-5/9= b)9/5-2/5= c)2/3-1/3= d)8/3-2/3= e)5/6+1/6= f)8/6+6/6= g)5/7-2/7=

Answer 1

a) 7/9 - 5/9 = 2/9

b)9/5 - 2/5 = 7/5

c) 2/3 - 1/3 = 1/3

d) 8/3 - 2/3 = 6/3  simplificando por 3 = 2/1 = 2


e) 5/6 + 1/6 = 6/6 =  1

f) 8/6 + 6/6 = 14/6 simplificando por 2 = 7/3

g) 5/7 - 2/7 =  3/7


Espero ter ajudado, boa tarde, bons estudos
