__________________
If we divide the amount boys OR girls ( depending on which gender) after the toal and move the decimal to the right twice after dividing) we will get our answer.
Formula:
(Amount of Boy or girls) = x
X/28
So since we are trying to get the percentages of boys, we will replace X with the amount of boys
21/28 = .75 ( then move the decimal to the right TWICE) = 75
Then you should get your percentages: 75% Also if your lookings for girls percentages, you basically subtract 75 ( boys percentages) with the total percentages ( 100) then you should get your answer for the girls: 25%

1/2 + 115 1/2 = 116.
9/10 - 5/10
because the denominators are the same you keep it and just subtract the numerators
=4/10
This can be reduced to 2/5

Answer:
x = 7 ± 
Step-by-step explanation:
Given
4(x - 7)² - 48 = 12 ( add 48 to both sides )
4(x - 7)² = 60 ( divide both sides by 4 )
(x - 7)² = 15 ( take the square root of both sides )
x - 7 = ± ( add 7 to both sides )
x = 7 ±
