Question

What percentage of (a) 9kg is 300g

Answer 1

Answer:

$3.33\%$

Step-by-step explanation:

Let x be the percentage

First convert both numbers to the same unit

300g = 300g

9kg = 9000g

Now, ATQ

$9000 \times \frac{x}{100} = 300$

We first cancel the zeroes from the numerator and the denominator in the LHS

$90x = 300$

Now we move 90 to the RHS

$x = \frac{300}{90}$

Now dividing 300 by 90, we get

$x = 3.33$

Note that the actual quotient goes on forever (3.33333333333333333333333...) but here we take the quotient upto 2 places of decimal places for our convenience

Hence the percentage is 3.33%
