Fiesta28 [93]

Answer:

Step-by-step explanation:

Students performing in the school concert=40%

let the students in the class be x

hence 40% of the class=12

where 40%=40/100=4/10=2/5 and of means multiplication

(2/5)*x=12

multiplying both sides by 5/2

hence the equation becomes

x=12*5/2

x=60/2

x=30

so the total students in the class are 30

There are 3/4 as many girls as there are boys.There are 63 students in the fifth grade. How many students are girls?

Answer:

<u>27</u> students are girls.

Step-by-step explanation:

Given:

There are 3/4 as many girls as there are boys.

In the fifth grade total there are 63 students.

Now, to find the number of students that are girls.

Let the number of students that are boys be $x.$

So, the number of students that are girls = $\frac{3}{4} \ of\ x=\frac{3x}{4} .$

Total number of students = 63.

Now, to get the number of students that are girls we solve an equation:

$x+\frac{3x}{4} =63\\\\\frac{4x+3x}{4} =63\\\\\frac{7x}{4} =63\\\\Multiplying\ both\ sides\ by\ 4\ we\ get:\\\\7x=252\\\\Dividing\ both\ sides\ by\ 7\ we\ get:\\\\x=36.$

Now, substituting the value of $x$ :

$\frac{3x}{4} \\\\=\frac{3\times 36}{4} \\\\=\frac{108}{4} \\\\=27.$

Therefore, 27 students are girls.
