What is<br> 3% of [(-0.5) * (- :)]<br> ?
expeople1 [14]
Solution for 0.5 is what percent of 3:

0.5:3*100 =

(0.5*100):3 =

50:3 = 16.666666666667

Now we have: 0.5 is what percent of 3 = 16.666666666667

Question: 0.5 is what percent of 3?

Percentage solution with steps:

Step 1: We make the assumption that 3 is 100% since it is our output value.

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

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

Step 4: In the same vein, $x\%=0.5$x%=0.5​.

Step 5: This gives us a pair of simple equations:

$100\%=3(1)$100%=3(1)​.

$x\%=0.5(2)$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

$\frac{100\%}{x\%}=\frac{3}{0.5}$
100%
x%​=
3
0.5​​

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

$\frac{x\%}{100\%}=\frac{0.5}{3}$
x%
100%​=
0.5
3​​

$\Rightarrow x=16.666666666667\%$⇒x=16.666666666667%​

Therefore, $0.5$0.5​ is $16.666666666667\%$16.666666666667%​ of $3$3​.

Solve and check please i need help
viktelen [127]

Answer:

e = 7.5

Step-by-step explanation:

Hi,

15 = e/0.5

You need to find what e equals. To do that, you need e all by itself. So to get e by itself in this equation, you need to multiply by 1/2 (same thing as 0.5). 15 x 0.5 is equal to 7.5.

To check your work, 7.5/0.5 is equal to 15.

So you know it's correct.

I hope this helps you :)
