Answer: Write the expression as:
" 70 [tex] \frac{32}{100} [/tex] +
2[tex] \frac{1}{10} [/tex] * 2[tex] \frac{7}{10[/tex] − 18a " ;
______________________________________________________
or; write as:
______________________________________________________
" 70.32 + (2.1) * (2.7) − 18a " ;
______________________________________________________
To simplify:
______________________________________________________
Using "PEDMAS" (the "order of operations") ;
the "multiplication" comes first;
So: → "(2.1) * (2.7) = 5.67 " .
And rewrite:
______________________________________________________
" 70.32 + 5.67 − 18a " .
Now: " 70.32 + 5.67 = 75.99 " ;
So, we can the final simplified expression as:
______________________________________________________
" 75.99 − 18a " ;
or; write as: " 75[tex] \frac{99}{100} [/tex] − 18a " .
