Answer 1

Answer:

the percentage of error is 96

Answer 2

Answer:

3600:20*100 =

(3600*100):20 =

360000:20 = 18000

Now we have: 3600 is what percent of 20 = 18000

Question: 3600 is what percent of 20?

Percentage solution with steps:

Step 1: We make the assumption that 20 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\%=20$100%=20.

Step 4: In the same vein, $x\%=3600$x%=3600.

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

$100\%=20(1)$100%=20(1).

$x\%=3600(2)$x%=3600(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{20}{3600}$100%x%=203600

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

$\frac{x\%}{100\%}=\frac{3600}{20}$x%100%=360020

$\Rightarrow x=18000\%$⇒x=18000%

Therefore, $3600$3600 is $18000\%$18000% of $20$20.
