Find the value of 2.5 % of 58​

Answer»

Answer:

Percentage Calculator: 2.5 is what percent of 58? = 4.3103448275862.

Step-by-step explanation:

Percentage solution with steps:

Step 1: We make the assumption that 58 is 100% since it is our output value.

Step 2: We next REPRESENT the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=58$.

Step 4: In the same vein, $x\%=2.5$.

Step 5: This gives us a pair of SIMPLE EQUATIONS:

$100\%=58(1)$.

$x\%=2.5(2)$.

Step 6: By simply DIVIDING equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{58}{2.5}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{2.5}{58}$

$\Rightarrow x=4.3103448275862\%$

Therefore, $2.5$ is $4.3103448275862\%$ of $58$.
