Answer 1

A) 1/3 de 240

$\frac{1}{3} .240 = \frac{240}{3} = 80$

B) 1/8 de 92

$\frac{1}{8} .92 = \frac{92}{8} = 11.5$

C)

$\frac{5}{6} - \frac{3}{4} =$

0,83 - 0,75 = 0,083...

D)

$\frac{3}{2} + \frac{2}{3} =$

1,5 + 0,66 = 2,16...

E)

$\frac{5}{20} \times \frac{4}{1} =$

$\frac{20}{20} = 1$

F)

$( \frac{1}{2} ) \div 2 =$

$\frac{1}{2} . \frac{1}{2} = \frac{1}{4}$
