Question

adição com denominadores iguais:a)4/3 +1/3 b)7/5 +1/5 c)8/7+1/7 d)3/9+1/9 e)2/8+1/8 f)6/3+5/3 g)14/4+1/4 h)4/6+1/6 i)4/10+3/10 j)3/5+6/5
​

Answer 1

Resposta:

a) 4/3 + 1/3 = 5/3

b) 7/5 + 1/5 = 8/5

c) 8/7 + 1/7 = 9/7

d)3/9+1/9 = 4/9

e)2/8+1/8 = 3/8

f)6/3+5/3 = 11/3

g)14/4+1/4 = 15/4

h)4/6+1/6 = 5/6

i)4/10+3/10 = 7/10

j)3/5+6/5 = 9/5

Explicação:

No caso de denominadores iguais, apenas se repete os denominadores e soma os numeradores.
