Question

4+(1/2+1/3) – (7/2⋅3/4)

Answer 1

Resposta:

$\frac{53}{24}$

Explicação passo-a-passo:

$4 + ( \frac{1}{2} + \frac{1}{3} ) - ( \frac{7}{2} . \frac{3}{4} ) =$

$4 + \frac{5}{6} - \frac{21}{8}$

m.m.c=

6, 8 : 2

3, 4 : 2

3, 2 : 2

3, 1 : 3

1, 1 então m.m.c = 2³.3= 8•3=24

$\frac{96 + 20 - 63}{24} = \frac{116 - 63}{24} = \frac{53}{24}$

Answer 2

Resposta:

53/24

Explicação passo a passo:

= 4+(1/2+1/3) – (7/2⋅3/4)

= 4 + 1/2 + 1/3 - 21/8

Mmc (2,3,8)= 24

2,3,8: 2

1,3,4: 2

1,3,2: 2

1,3,1: 3

1,1,1

= 2.2.2.3

= 8.3

= 24

= (24.4 + 12 + 8 - 3.21)/24

= (96+20-63)/24

= (116-63)/24

= 53/24
