Question

resolva as frações:

1-a) 1+ 2/3 : 3/5 - 1/3 =

2-a)A=1/3² b= 2/3²
então o valor de a e b será:

a)6/50

b)7/35

C)6/25

D)1/4​

Answer 1

Resposta:

Explicação passo-a-passo:

Olá!!

$1)\\\\1+\frac{2}{3}\div\frac{3}{5}-\frac{1}{3}\\ \\1+\frac{2}{3}\times\frac{5}{3}-\frac{1}{3}\\\\1+\frac{10}{9}-\frac{1}{3}\\\\\frac{1+\frac{10}{9}-\frac{1}{3}}{9}\\\\\frac{9+10-3}{9} \\\\\checkmark\boxed{\Rightarrow\boxed{\frac{16}{9}}}$

=>>

$2)\\\\a)\\{(\frac{1}{3})^{2}=> \frac{1^{2}}{3^{2} } =>>\checkmark\boxed{\Rightarrow\boxed{\frac{1}{9}}}$

$b)\\{(\frac{2}{3})}^{2} =>(\frac{2^{2} }{3^{2} })=>>\checkmark\boxed{\Rightarrow\boxed{\frac{4}{9}}}$

Answer 2

1. a) 1 + 2/3 : 3/5 - 1/3

⠀⠀1 + 2/3 × 5/3 - 1/3

⠀⠀1 + 10/9 - 1/3

⠀⠀19/9 - 1/3

⠀⠀16/9

2. A + B

⠀(1/3)² + (2/3)²

⠀1²/3² + 2²/3²

⠀1/8 + 4/9

⠀5/9
