At a middle school, 75% of the sixth-grade students attended the first dance. If there were 105 sixth graders at the dance, how many students are in sixth grade?

140 students in the sixth grade

Step-by-step explanation:

75%= 105 sixth graders

since 75% is 3/4 of 100%

u can find 25% and then add that to 75% to find how many there are:

75/3= 25

105/3=35

25% = 35 sixth graders

25% *4 =100%

35*4= 140

108 six grade students.

Step-by-step explanation: First looked at how many six graders at the middle school is 75% and add how many more six graders to the school dance. The answer is 180 six graders attended to the school dance.
