Answer 2

Let's solve each of these expressions step by step:

1. $312:4*9-480:16*5$

   First, perform the divisions and multiplications from left to right:

   $78 * 9 - 30 * 5$

   Then, do the multiplications:

   $702 - 150$

   Finally, subtract:

   $702 - 150 = 552$

2. $900:5:4+117*7:3$

   Start with the divisions and multiplications from left to right:

   $(180) + (819/3)$

   Now, calculate the addition and division:

   $180 + 273 = 453$

3. $12000-(18*54+1048)$

   First, perform the multiplications and additions inside the parentheses:

   $12000 - (972 + 1048)$

   Then, calculate the sum inside the parentheses:

   $12000 - 2020$

   Finally, subtract:

   $12000 - 2020 = 9980$

4. $7150-800*(375:75)$

   Start with the division inside the parentheses:

   $7150 - 800 * 5$

   Now, perform the multiplication:

   $7150 - 4000$

   Finally, subtract:

   $7150 - 4000 = 3150$

So, the results are:

1. $312:4*9-480:16*5 = 552$
2. $900:5:4+117*7:3 = 453$
3. $12000-(18*54+1048) = 9980$
4. $7150-800*(375:75) = 3150$

These are the values of the expressions after performing the specified operations.
