There were 320 girls and 180 boys at a theater. What percent of children were girls

64% were girls

Step-by-step explanation:

Add 320 with 180

320+180=500

take 500 and divide it by 320

320/500 = 64%

64% of the children were girls

Step-by-step explanation:

This is true because out of 500 children total 320 are girls, so what we do is first multiply all values by 2 so that we can get our result easier. 320x2=640, 180x2=360, and 500x2=1000, this makes things simpler because 50 is half of 100 so now we have something that is easier to calculate with because now if we remove 1 zero from each number we will get 36,64, and 100 so out of 100%, 64% are girls

Hope this Helps, Your Welcome, And Have An Amazing Day!!!
