Question

resolver:

$4 \frac{1}{2} \div 3 \frac{4}{5}$
$\sqrt{5 \frac{4}{9} } + \sqrt{2 \frac{1}{4} }$
​

Answer 1

Respuesta:

a) $\frac{45}{38}$

b) $\frac{23}{6}$

Explicación paso a paso:

a)

     $4\frac{1}{2}\div3\frac{4}{5}\\\\\frac{9}{2}\div\frac{19}{5}\\\\\frac{9}{2}*\frac{5}{19}\\\\\frac{9*5}{2*19}\\\\\frac{45}{38}$                    

b)

       $\sqrt{5\frac{4}{9}}+\sqrt{2\frac{1}{4}}\\\\\sqrt{\frac{49}{9}}+\sqrt{\frac{9}{4}}\\\\\frac{\sqrt{49}}{\sqrt{9}}+\frac{\sqrt{9}}{\sqrt{4}}\\\\\frac{7}{3}+\frac{3}{2}\\\\\frac{(7*2)+(3*3)}{6}\\\\\frac{14+9}{6}\\\\\frac{23}{6}$
