Answer 1

Answer:

Step-by-step explanation:

57) Order of operation: First what is inside the parenthesis - so division and then subtraction

For fraction division use KCF method

Keep the first fraction

Change division to multiplication

Flip the second fraction

$(\frac{5}{8}$ ÷ $\frac{1}{4})$ - ($\frac{4}{5}$ ÷ $\frac{1}{2})$ = $(\frac{5}{8}*\frac{4}{1})-(\frac{4}{5}*\frac{2}{1})$

                      $= (\frac{5}{2})-(\frac{8}{5})$

                      $= \frac{5*5}{2*5} -\frac{8*2}{5*2}\\\\=\frac{25}{10}-\frac{16}{10}\\\\= \frac{9}{10}$

59)

$\frac{3}{4} +\frac{1}{3} = \frac{3*3}{4*3}+\frac{1*4}{3*4}$

         $=\frac{9}{12}+\frac{4}{12}\\\\= \frac{9+4}{12}\\\\= \frac{13}{12}$

$(\frac{3}{4}+\frac{1}{3})-\frac{9}{15}=\frac{13}{12}-\frac{3}{5}$

                    $= \frac{13*5}{12*5}-\frac{3*12}{5*12}\\\\= \frac{65}{60}-\frac{48}{60}\\\\= \frac{65-48}{60}\\\\= \frac{17}{60}$

Answer 2

Step-by-step explanation:

Divide them up, and then after that, the parenthesis mean that you need to multiply them! So I hope that helps!
