Question

resolva as seguintes frações

5/6 - 1/4=

5/6 -3/10 =

2/6 - 1/15=

Answer 1

$\frac{5}{6} - \frac{1}{4} =$

6,4 | 2

3,2 | 2

3,1 | 3

1,1 MMC 2×2×3 =

MMC 4×3 = 12

$\frac{10 - 3}{12} =$

$\frac{7}{12} = 0.58$

$\frac{5}{6} - \frac{3}{10} =$

6,10 | 2

3,5 | 3

1,5 | 5

1,1 MMC 2×3×5 =

MMC 6×5 = 30

$\frac{25 - 9}{30} =$

$\frac{16( \div 2)}{30( \div 2)} =$

$\frac{8}{15} = 0.53$

$\frac{2}{6} - \frac{1}{15} =$

6,15 | 2

3,15 | 3

1,5 | 5

1,1 MMC 2×3×5 =

MMC 6×5 = 30

$\frac{10 - 2}{30} =$

$\frac{8( \div 2)}{30( \div 2)} =$

$\frac{4}{15} = 0.26$

Answer 2

Resposta:

Explicação passo a passo:

5/6 - 1/4=

*= (2.5-3.1)/12"

" =(10-3)/12"

="7/12 "

_____________

5/6 - 3/10 =

= "(5.5-3.3)/30"

= "(25-9)/30"

= "16/30" (:2)/(:2)

= "8/15"

________

2/6 - 1/15=

= (5.2-2)/30""

= (10-2)/30"

= 8/30 (:2)/(:2)

= "4/15*
