Question

how 0.5 × 10 = 5 how???​

Answer 1

Step-by-step explanation:

Solution for 0.5 is what percent of 10:

0.5:10*100 =

(0.5*100):10 =

50:10 = 5

Now we have: 0.5 is what percent of 10 = 5

Question: 0.5 is what percent of 10?

Percentage solution with steps:

Step 1: We make the assumption that 10 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 $100\%=10$.

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

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

$100\%=10(1)$.

$x\%=0.5(2)$.

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

$\frac{100\%}{x\%}=\frac{10}{0.5}$

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

$\frac{x\%}{100\%}=\frac{0.5}{10}$

$\Rightarrow x=5\%$

Therefore, $0.5$ is $5\%$ of $10$.

Answer 2

Step-by-step explanation:

It's because, 0.5 is a decimal you move the decimal since you times it by 10. If you do 0.5 x 100, that will be 50. If you do 0.5 x 1000 it will be 500. Any decimal multiplied by the 10's, 100's, 1000's you move the decimal to the right! Simple. Also, I did draw it to show, if you don't understand it. :) I tried my best, to do the clearest explanation, I hope this helps!
