10/3 ÷ 5/9 =
​

Answer 1

Resposta:

Explicação passo a passo:

Simplifique as frações

14/3 / (2 1/3) =

= 14/3 ÷ (3.2+1)/3

= 14/3 ÷ 7/3

= 14/3 . 3/7

= 14/7 . 3/3

= 2 . 1

= 2

81/5 ÷ 27/25 =

= 81/5 . 25/27

= 81/27 . 25/5

= 3 . 5

= 15

10/3 ÷ 5/9 =

= 10/3 . 9/5

= 9/3 . 10/5

= 3 . 2

= 6

Answer 2

Resposta:

$\frac{14}{3} :2\frac{1}{3}\\\\\frac{14}{3}\div \frac{7}{3}\\\\\frac{14}{3}\times \frac{3}{7}\\\\\frac{14\times \:3}{3\times \:7}\\\\\frac{14}{7}\\\\=2$

$\frac{81}{5}:\frac{27}{25}\\\\\frac{81}{5}\times \frac{25}{27}\\\\\frac{81\times \:25}{5\times \:27}\\\\\frac{2025}{5\times \:27}\\\\\frac{2025}{135}\\\\=15$

$\frac{10}{3}:\frac{5}{9}\\\\\frac{10}{3}\times \frac{9}{5}\\\\\frac{10\times \:9}{3\times \:5}\\\\\frac{90}{3\times \:5}\\\\\frac{90}{15}\\\\=6$
