Question

x- 30% =900
what is x?

Answer 1

Answer:

30 percent * 900 =

(30:100)* 900 =

(30* 900):100 =

27000:100 = 270

Now we have: 30 percent of 900 = 270

Question: What is 30 percent of 900?

Percentage solution with steps:

Step 1: Our output value is 900.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$900=100\%$.

Step 4: Similarly, $x=30\%$.

Step 5: This results in a pair of simple equations:

$900=100\%(1)$.

$x=30\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{900}{x}=\frac{100\%}{30\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{900}=\frac{30}{100}$

$\Rightarrow x=270$

Therefore, $30\%$ of $900$ is $270$
