Vamos corrigir e calcular cada uma das expressões fornecidas:<br /><br />(a) \(80\% \) de 300:<br />\[ 0,80 \times 300 = 240 \]<br /><br />(b) \(150\% \) de 200:<br />\[ 1,50 \times 200 = 300 \]<br /><br />(c) \(701\) do \(700\):<br />\[ \frac{701}{700} \approx 1,003 \]<br /><br />(d) \(4001\) do \(200\):<br />\[ \frac{4001}{200} = 20,005 \]<br /><br />(e) \(25\% \) de 100:<br />\[ 0,25 \times 100 = 25 \]<br /><br />(f) \(1301: 000300\):<br />\[ \frac{1301}{300} \approx 4,337 \]<br /><br />(g) \(301 - de 1:800\):<br />\[ 301 - \frac{1}{800} = 301 - 0,00125 = 300,99875 \]<br /><br />(h) \(120\% \) de 800:<br />\[ 1,20 \times 800 = 960 \]<br /><br />(i) \(901\) colo60:<br />\[ 901 \times 60 = 54060 \]<br /><br />(j) \(751 d400\):<br />\[ \frac{751}{400} \approx 1,8785 \]<br /><br />Portanto, as respostas corrigidas são:<br /><br />(a) \(80\% \) de 300 = 240<br /><br />(b) \(150\% \) de 200 = 300<br /><br />(c) \(701\) do \(700\) = 1,003<br /><br />(d) \(4001\) do \(200\) = 20,005<br /><br />(e) \(25\% \) de 100 = 25<br /><br />(f) \(1301: 000300\) = 4,337<br /><br />(g) \(301 - de 1:800\) = 300,99875<br /><br />(h) \(120\% \) de 800 = 960<br /><br />(i) \(901\) colo60 = 54060<br /><br />(j) \(751 d400\) = 1,8785
