Question

1/2%ofx=9 find the value of X when​

Answer 1

Given: 1/2% × x = 9

--> 1/200 × x = 9

--> x = 9 × 200 (reciprocal)

--> x = 1800

∴ Value of X = 1,800

Answer 2

Given: $1/2\%\ of\ x=9$

We have to find the value of$x$.

• As we know that a percentage is a fraction of an amount is expressed as a particular number of hundredths of that amount.
• It is denoted by a symbol%.
• For example, $5$%means$\frac{5}{100}$.
• By using the unitary method we are calculating the percentage of numbers.
• As we know fractions can be converted into percentages and vice-versa.
• And percentages are reversible.  
• For example, $50 \% \ of\ 60$ is the same as$60 \% \ of\ 50$.

We are solving in the following way:

$1/2\%\ of\ x=9$

$=>\frac{1}{2} \div 100\times x=9\\\\=>\frac{1}{2} \times\frac{1}{100} \times x=9\\\\=>\frac{1}{200} \times x=9\\\\=>\frac{x}{200} =9\\\\=>x=9\times 200\\\\=>x=1800$

Hence, we get $1/2\%\ of\ 1800=9$
