(6 - 2) - 1 = 4 - 1 = 3

6 - (2 - 1) = 6 - 1 = 5

The associative rule doesn't work for subtraction because you get different results when you move the parentheses.

%of 25 is 14.<br><br> what percent of 20 is 11?<br><br> 15 is
ikadub [295]
The first question:

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

\frac{x}{100} \times 25 = 14\\\\\frac{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

\frac{x}{100} \times 20 = 11\\\\\frac{x}{5} = 11\\\\\boxed{\bf{x = 55}}

55% of 20 is 11<span>.</span>
