what percent of 20 is 11?

15 is what percent of 5

Answer 1

The first question:

'is' in mathematics means equal
'of' in mathematics means multiplication


`(x)/(100) * 25 = 14\\\\(x)/(4) = 14\\\\\boxed{\bf{x=56}}`

56% of 25 is 14.

And the second question:

'is' in mathematics means equal
'of' in mathematics means multiplication


`(x)/(100) * 20 = 11\\\\(x)/(5) = 11\\\\\boxed{\bf{x = 55}}`

55% of 20 is 11.

And finally, the third question:

'is' in mathematics means equal
'of' in mathematics means multiplication


`15 = (x)/(100) * 5\\\\15 = (x)/(20)\\\\\boxed{\bf{x=300}}`

15 is 300% of 5.
