SOLUTION:
Step 1 :
In this question, we are meant to find what percent of 142 is 58.
Step 2 :
We make the assumption that 142 is 100 % since it is our output value.
Step 3:
We next represent the value we see with x.
Step 4 :
From step 2, it follows that 100 % = 142.
Step 5 :
In the same vein, x % = 58.
Step 6 :
This gives us a pair of simple equations:
![\begin{gathered} 100\text{ \% = 142 ---- equ 1} \\ x\text{ \% = 58 }\ldots\ldots\ldots\ldots\text{ equ 2} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/lk1785n06jjckc6kos7xia0c8smtsz3wo3.png)
Step 7 :
By simply dividing equation 1 by equation 2 and
taking note of the fact that the Left-Hand Side of both equations have the same unit ( % ), we have that :
![\frac{100\text{ \%}}{x\text{ \%}}\text{ = }(142)/(58)](https://img.qammunity.org/2023/formulas/mathematics/college/jenf5nqw43jukvrn3u1f7s9j924s49g29w.png)
Step 8 :
Taking the inverse ( or reciprocal ) of both sides yields:
![\frac{x\text{ \%}}{100\text{ \%}}\text{ = }(58)/(142)](https://img.qammunity.org/2023/formulas/mathematics/college/prgvgs8is1r6f8ih0y8f6g21ril867dpa3.png)
![\begin{gathered} x\text{ = }\frac{58\text{ x 100}}{142} \\ \text{x = }(5800)/(142) \\ x\text{ = 40.85\%} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/8apmwrkgm8kghv92wis1akuo69uczcx7hf.png)
CONCLUSION:
Therefore, 58 is 40.85 % of 142.
