ANSWER
90,400.5
Step-by-step explanation
To add these factors, first, we have to solve the multiplications in the parenthesis,
![(9\cdot10,000)+(2\cdot100)+(2\cdot100)+(5\cdot(1)/(10))=90,000+200+200+(5)/(10)](https://img.qammunity.org/2023/formulas/mathematics/college/gzn0uikqpl6bceodu55oymm66e766jo08c.png)
Note that the last term is a fraction, so first, we have to simplify it. Both numerator and denominator are divisible by 5, thus,
![(5)/(10)=(1)/(2)](https://img.qammunity.org/2023/formulas/mathematics/college/foc5cwx68ard9xnxlc3tmpmsgub5gejmez.png)
Add the whole numbers first,
![90,000+200+200+(1)/(2)=90,400+(1)/(2)](https://img.qammunity.org/2023/formulas/mathematics/college/lqedq6prtxisaxsh69dpwza40czlwcyddg.png)
Then we can either add the fraction so the answer is another fraction with a rather large numerator, or we can add the fraction as a decimal,
![(1)/(2)=0.5](https://img.qammunity.org/2023/formulas/mathematics/high-school/4h36bsuwugqz27yh65chi8lib8t3ohhqw5.png)
And the result is,
![90,400+0.5=90,400.5](https://img.qammunity.org/2023/formulas/mathematics/college/ads0xxmp0sqnccmbplfmfbqw3tvjnm54wk.png)
If we add the fraction and express the answer as an improper fraction we have,
![90,400+(1)/(2)=(2\cdot90,400+1)/(2)=(180,800+1)/(2)=(180,801)/(2)](https://img.qammunity.org/2023/formulas/mathematics/college/ej5m878ii0bkdvzqi6yj2180t0d1zgy4bi.png)
Or we can also write it as a mixed number,
![90,400+(1)/(2)=90,400(1)/(2)](https://img.qammunity.org/2023/formulas/mathematics/college/7xr1yrbu7c2dfmfgfig40f753tgscrjly2.png)
