A realtor makes a commission of $11,400 on a $190,000 house he sells. What is his commission rate?

So bassically

his commision rate is

x% times 190000=comission

so x% times 190000=11400

divide both sdies by 190000

x%=11400/190000

solve for x percent

11400/190000=114/1900=3/50

x%=3/50

percent means parts out of 100 so x%=x/100

x/100=3/50

3/50=6/100

x/100=6/100

multiply both sdies by 100

x=6

the commision rate is 6%
