There are 1,500 students in a school. 65% are girls. how many girls are there in the school?

The answer is:  " 975 girls " .

Explanation:

What is 65% of 1500?

  65/100 * 1500/1 = ?  ;

The two "zeros" in "100" cancel out;  
and the two "zeros" in "1500" cancel out;

    And we are left with:

    65/1  * 15/1 = 65 * 15 = 975 girls.

OTHER METHOD:

   65% of 1500 = 65/100 * 1500 = 0.65 * 1500 = 975 girls.

OTHER Method:

  65% of 1500 = 65/100 * 1500 ;

Note:  65/100 = (65÷5) / (100÷5) = 13/20;

13/20 * 1500 = 13/20 * 1500/1 = ? ;

 The "zero" in "20" cancels out; and the last zero in "1500" cancels out;

and we have:  13/2 * 150/1 ;  

The "2" cancels to a "1" ; and the "150" cancels to a "75"; 

and we have:  13/1 * 75/1 = 13 * 75 = 975 .
