Answer:
![\frac{17}{80}](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B80%7D)
Step-by-step explanation:
we have
![21\frac{1}{4}\%](https://tex.z-dn.net/?f=21%5Cfrac%7B1%7D%7B4%7D%5C%25)
Convert mixed number to an improper fraction
![21\frac{1}{4}=21+\frac{1}{4}=\frac{21*4+1}{4}=\frac{85}{4}](https://tex.z-dn.net/?f=21%5Cfrac%7B1%7D%7B4%7D%3D21%2B%5Cfrac%7B1%7D%7B4%7D%3D%5Cfrac%7B21%2A4%2B1%7D%7B4%7D%3D%5Cfrac%7B85%7D%7B4%7D)
so
![21\frac{1}{4}\%=\frac{85}{4}\%](https://tex.z-dn.net/?f=21%5Cfrac%7B1%7D%7B4%7D%5C%25%3D%5Cfrac%7B85%7D%7B4%7D%5C%25)
Convert percent number as a fraction
![\frac{85}{4}\%=\frac{85}{4}:100=\frac{85}{4*100}=\frac{85}{400}](https://tex.z-dn.net/?f=%5Cfrac%7B85%7D%7B4%7D%5C%25%3D%5Cfrac%7B85%7D%7B4%7D%3A100%3D%5Cfrac%7B85%7D%7B4%2A100%7D%3D%5Cfrac%7B85%7D%7B400%7D)
Simplify
Divide by 5 both numerator and denominator
![\frac{17}{80}](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B80%7D)

Answer:
x = 73
General Formulas and Concepts:
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define equation</u>
(180 - x) + (90 - x) = 124
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 270 - 2x = 124
- Subtract 270 on both sides: -2x = -146
- Divide -2 on both sides: x = 73
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: (180 - 73) + (90 - 73) = 124
- Subtract: 107 + 17 = 124
- Add: 124 = 124
