why if else doesn't respond in c

when grossPay pass into find tax amount,seem like tax if else doesn't receive it...result is 0.0000 how can i solve this??

float grossPay = 400;


float taxPhase1 = 0;
float taxPhase2 = 0;
float taxPhase3 = 0;
float totalTax = 0;

if(grossPay<=300)
{
    taxPhase1 = ((float)(grossPay)*(15/100));
    totalTax = taxPhase1;
}
else if(grossPay>300 && grossPay<=450)
{
    taxPhase1 = ((float)300*(15/100));
    taxPhase2 = ((float)(grossPay-300)*(20/100));
    totalTax = (taxPhase1 + taxPhase2);
}

else if(grossPay>450)
{
    taxPhase1 = ((float)300*(15/100));
    taxPhase2 = ((float)150*(20/100));
    taxPhase3 = ((float)(grossPay-450)*(25/100));
    totalTax = (taxPhase1 + taxPhase2 + taxPhase3) ;
}

  printf("%f",totalTax);

Code has several instances of integer division errors such as:

15/100

Which all result in zero, resulting in incorrect evaluations

taxPhase1 = ((float)(grossPay)*(15/100));//result == 0

Change to

15.0/100  or 15/100.0 (for all occurrences.)

taxPhase1 = ((float)(grossPay)*(15/100.0));//result = 60.0 (gross pay == 400)
