Question

Assinale as alternativas que representam uma igualdade:

 

(  ) 2 + 4 = 3 + 1

(  ) 3 – 1 = 3 + 1

(  ) 2 + 1 = 1 + 2

(  ) 8 – 1 = 8 + 1

(  ) 8 – 3 = 3 + 2

(  ) 5 – 3 = 3 + 1

(  ) 5 – 1 = 6 + 1

(  ) 5 + 2 = 10 – 3

(  ) 9 – 3 = 6 + 1

​

Answer 1

(  ) 2 + 4 = 3 + 1

(  ) 3 – 1 = 3 + 1

( x ) 2 + 1 = 1 + 2

(  ) 8 – 1 = 8 + 1

(x  ) 8 – 3 = 3 + 2

(  ) 5 – 3 = 3 + 1

(  ) 5 – 1 = 6 + 1

( x ) 5 + 2 = 10 – 3

(  ) 9 – 3 = 6 + 1

Boa sorte
