Answer 1

Resposta:

a)

$\sf \dfrac{\dfrac{1}{3} + 0,5 }{\dfrac{3}{2} + \dfrac{1}{4} } = \left (\dfrac{1}{3} + \dfrac{5}{10} \right) \div \left (\dfrac{3}{2} + \dfrac{1}{4} \right) = \left (\dfrac{10}{30} + \dfrac{15}{30} \right) \div \left (\dfrac{6}{4} + \dfrac{1}{4} \right) =$

$\sf \dfrac{\dfrac{1}{3} + 0,5 }{\dfrac{3}{2} + \dfrac{1}{4} } = \dfrac{25}{30} \div \dfrac{7}{4} = \dfrac{25}{30} \times \dfrac{4}{7} = \dfrac{100}{210} = \boldsymbol{ \dfrac{10}{21} }$

b)

$\sf \dfrac{\dfrac{5}{3} +\dfrac{1}{2} }{1 +0,5 } = \left (\dfrac{5}{3} + \dfrac{1}{2} \right) \div \left (1+0,5 \right) = \left (\dfrac{10}{6} + \dfrac{3}{6} \right) \div \left (2,5 \right) =$

$\sf \dfrac{\dfrac{5}{3} +\dfrac{1}{2} }{1 +0,5 } = \left (\dfrac{10}{6} + \dfrac{3}{6} \right) \times \left (\dfrac{25}{10} \right) = \dfrac{13}{6} \times \dfrac{10}{25} = \dfrac{130}{150} = \boldsymbol{ \dfrac{13}{15} }$
