The order of mathematical operations can be used to give;
Part A:
[tex] \frac{22}{0.25} - \frac{12.6}{6} [/tex]
Part B:
[tex] 88 - 2.1 [/tex]
The given expression is presented as follows;
[tex] \frac{{4}^{2} + 6}{ | - 0.25|} - \frac{12.6}{6} [/tex]
The steps are presented as follows;
Step 1
[tex] \frac{{4}^{2} + 6}{ | - 0.25|} - \frac{12.6}{6} [/tex]
Step 2
[tex] \frac{{4}^{2} + 6}{ 0.25} - \frac{12.6}{6} [/tex]
Step 3
[tex] \frac{16 + 6}{0.25} - \frac{12.6}{6} [/tex]
Step 4
[tex] \frac{22}{0.25} - \frac{12.6}{6} [/tex]
Step 5
[tex] 88 - \frac{12.6}{6} [/tex]
Step 6
[tex] 88 - 2.1 [/tex]
Step 7
85.9
Which gives;
Part A: The missing expression for step 4 is therefore;
[tex] \frac{22}{0.25} - \frac{12.6}{6} [/tex]
Part B: The missing expression for step 6 as presented above is the expression;
[tex] 88 - 2.1 [/tex]
