There are 77 students in the student council. The ratio of girls to boys is 7:4. How many girls are in the student council?
number of girls --- 7x
numbero boys ---- 4x
7x + 4x = 77
11x = 77
x= 7
so we have 49 girls and 28 boys

To find out how many girls are in the student council, we first need to calculate the number of parts in the ratio for girls. The ratio of girls to boys is given as 7:4, which means there are 7 parts for girls and 4 parts for boys.
Next, we need to determine the value of each part. To do this, we divide the total number of parts (7 + 4) into the total number of students in the student council, which is 77:
Total number of parts = 7 + 4 = 11
Value of each part = Total number of students / Total number of parts = 77 / 11 = 7
Now that we know the value of each part, we can find the number of girls by multiplying the value of each part (7) by the number of parts for girls (7):
Number of girls = Value of each part * Number of parts for girls = 7 * 7 = 49
Therefore, there are 49 girls in the student council.
