Step-by-step work:
195 calories is the total amount of calories in the chicken nuggets and 117 calories are from fat so you could write that as:
117/195
now remember that a “/“ also means divide, so divide the fraction:
117/195 = 0.6
0.6 is the decimal form of 117/195
then since percentages are out of 100, you multiply it by 100:
0.6 • 100 = 60
and 60% is your final answer!
