Answer 1

1)
$frac{25}{4}(2 - frac{33}{8} = frac{50}{8} - frac{33}{8} = frac{17}{8}$
2)
$frac{17}{8} times 4 = frac{68}{8}$
$frac{10}{3} div frac{7}{3 } = frac{10}{3} times frac{3}{7} = frac{10}{7}$
4)
$frac{68}{8}(7 + frac{10}{7}(8 = frac{476}{56} + frac{80}{56} = frac{556}{56} = frac{278}{28} = frac{139}{14}$
