Answer:
15 is the short answer
Explanation:
Solution for 0.5 is what percent of 7.5:
0.5:7.5*100 =
(0.5*100):7.5 =
50:7.5 = 6.6666666666667
Now we have: 0.5 is what percent of 7.5 = 6.6666666666667
Question: 0.5 is what percent of 7.5?
Percentage solution with steps:
Step 1: We make the assumption that 7.5 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 $100\%=7.5$.
Step 4: In the same vein, $x\%=0.5$.
Step 5: This gives us a pair of simple equations:
$100\%=7.5(1)$.
$x\%=0.5(2)$.
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
$\frac{100\%}{x\%}=\frac{7.5}{0.5}$
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{0.5}{7.5}$
$\Rightarrow x=6.6666666666667\%$
Therefore, $0.5$ is $6.6666666666667\%$ of $7.5$.
