VAMOS A SUA PERGUNTA:⇒⇒

$\sf \: ( 4 \dfrac { 3 } { 10 } + 2 \dfrac { 1 } { 5 } ) \div \dfrac{ 1 }{ 4 }$

$\sf \: \dfrac{\dfrac{40+3}{10}+\dfrac{2\times 5+1}{5}}{\dfrac{1}{4}}\approx 26$

$\sf\dfrac{\dfrac{43}{10}+\dfrac{2\times 5+1}{5}}{\dfrac{1}{4}}\approx 26$

$\sf\dfrac{\dfrac{43}{10}+\dfrac{10+1}{5}}{\dfrac{1}{4}}\approx 26$

$\sf \: \dfrac{\dfrac{43}{10}+\dfrac{11}{5}}{\dfrac{1}{4}}\approx 26$

$\sf\dfrac{\dfrac{43}{10}+\dfrac{22}{10}}{\dfrac{1}{4}}\approx 26$

$\sf\dfrac{\dfrac{43+22}{10}}{\dfrac{1}{4}}=26$

$\sf \: \dfrac{\dfrac{65}{10}}{\dfrac{1}{4}}=26$

$\sf \: \dfrac{\dfrac{13}{2}}{\dfrac{1}{4}}=26$

$\sf \: \dfrac{13}{2}\times 4=26$

$\sf\dfrac{13\times 4}{2}=26$

$\sf\dfrac{52}{2}=26$

$\boxed{\bold{\displaystyle{\clubsuit\ \spadesuit\ \maltese  \sf \red{ = 26}}}}\ \checkmark$← RESPOSTA.
