Answer 1

Answer:

65% and 11.11%

Step-by-step explanation:

As we have given in the question we need to find the percentage of 1st quantity concerning 2nd quantity, The question is easy but to solve the question we should have good knowledge about the percentages

So if we consider 1st part we can calculate it by formula

$\dfrac{x}{100}\times11.2=7.28$

So by the above equation, The value of x will be

$x=65%$

Now let's consider 2nd part, The equation will be

$\dfrac{x}{100}\times22.5=2.5$

So from the above equation x comes out to be

$x=11.11%$
