Answer:

40%

Step-by-step explanation:

add both numbers together to get the total amount of guests

170 + 255 = 425

divide the number of guests who called for room service by the total guests

170 ÷ 425 = 0.4

convert the decimal to a percentage

0.4 = 40%

(This is how I was taught.)

Part : 170
Whole : 255
Percent :

170/255 • x/100

(• is the multiplication sign, And you have to cross multiply 170/255 and x/100.)

17,000/255x is what you’ll get, So now you divide, So your answer is 66.66666667% , BUT write 66.67% (:
