metodo da borboleta alguém me ajuda??​

Answer 1

Resposta:

Explicação passo-a-passo:

2/3+1/2 = (2.2+3.1)/6 = (4+3)/6=7/6

2/3+3/4 = (4.2+3.3)/12 = (8+9)/12= 17/12

2/3+2/5= (5.2+3.2)/15= (10+6)/15= 16/15

1/5+1/2 = (2+5)/10= 7/10

1/5+3/4 = (4+5.3)/20 = (4+15)/20=19/20

1/5 + 2/5 = 3/5

3/2+1/2 = 4/2 = 2

3/2+3/4 = (2.3+3)/4= (6+3)/4= 9/4

3/2+2/5 = (5.3+2.2)/10 = (15+4)/10=19/10

2/3-1/2 = (2.2-3)/6 = (4-3)/6 =1/6

2/3-2/5 = (5.2-3.2)/15=(10-6)/15=4/15

2/3-1/5 = (5.2-3)/15 = (10-3)/15= 7/15

3/4 - 1/2 = (3-2)/4 = 1/4

3/4 - 2/5 =(5.3 - 4.2)/20 =(15-8)/20=7/20

3/4 - 1/5 = (5.3-4)/20= (15-4)/20= 11/20

3/2 - 1/2 = 2/2 = 1

3/2 - 2/5 = (5.3-2.2)/10=(15-4)/10=11/10

3/2 - 1/5 = (5.3-2.1)/10 = (15-2)/10= 13/10
