Question

Me ajudem nessas equações

Answer 1

Explicação passo-a-passo:

(1/3 +1/4)÷ 5/2 +2/3 = 9/10

(4/12 + 3/12) ÷ 5/2+2/3= 9/10

7/12 ÷ 5/2+2/3 = 9/10

7/12 × 2/5 +2/3= 9/10

7/6 × 1/5+2/3=9/10

7/30 +2/3= 9/10

7+20/30= 9/10

27/30= 9/10

27÷ 3

____= 9/10

30÷ 3

9/10=9/10

4/9 +4 +1/3 -1/2= 77/18

8+72+6-9/18= 77/18

86 -9/18= 77/18

77/18= 77/18
