 $\left(10\times3\right)+\left(12\div4+15\right)\div3$  
After the 2nd simplifying step, the expression is:

•  $30+\left(12\div19\right)\div3$  

•  $30+\left(4+15\right)\div3$  

•  $30+\left(3+5\right)$  

•  $30+\left(3+15\right)\div3$

Simplify $\left[5\left(\frac{4}{5}\times\frac{2}{3}\right)\right]\div4$  then answer the next 3 questions. 

After the 1st step, the simplified expression is:

•  $\left[5\left(\frac{6}{8}\right)\right]\div4$  

•  $\left[5\left(\frac{8}{15}\right)\right]\div4$  

•  $\left[\frac{20}{25}-\frac{10}{15}\right]\div4$  

•  $\left[5\left(\frac{15}{8}\right)\right]\div4$

 $\left[5\left(\frac{4}{5}\times\frac{2}{3}\right)\right]\div4$   $\rightarrow$   $\left[5\left(\frac{8}{15}\right)\right]\div4$  
 After the next step, the simplified expression is:

•  $\frac{15}{40}\div4$  

•  $\frac{40}{5}\div4$  

•  $\frac{40}{15}\div4$  

•  $\frac{13}{15}\div4$  

 $\left[5\left(\frac{4}{5}\times\frac{2}{3}\right)\right]\div4$  $\rightarrow$   $\left[5\left(\frac{8}{15}\right)\right]\div4$   $\rightarrow$   $\frac{40}{15}\div4$   $\rightarrow$    $?$
