40% of the students in a class are girls and the number of boys is 24 find the total number of students and the number of girls

navik [9.2K]

Answer:

Girls = 16

Total students = 40

Step-by-step explanation:

40% of the students are girls, this means 60% of the students are boys.

To find the number of girls, setup a proportion using the percentages and actual number of students in the class. I am going to make the numerator the numbers that go with the girls and the denominator will be the numbers that go with the boys.

Also let's convert the percentages to decimals by moving the decimal two places left.

40% = 0.4 and 60% = 0.6

$\frac{.4}{.6} =\frac{g}{24} \\.6g=9.6\\\frac{.6g}{.6} =\frac{9.6}{.6} \\g=16$

Now let's find the total number of students by adding the number of girls to the number of boys.

16 + 24 = 40

Solve for T V = x + at

iris [78.8K]

Answer:

t=V‒x/a

Step-by-step explanation:

V=x+at (add ‒x in both side)

V‒x=x+at‒x

V‒x=at

V‒x/a=at/a

V‒x/a=t

so the formula is t=V‒x/a
