Step-by-step explanation:
Explanation:
First, multiply each side of the equation by
2
to eliminate the fraction while keeping the equation balanced:
2
×
A
=
2
×
h
2
(

A
=

h
2
(
a
+
b
)
2
A
=
h
(
a
+
b
)
Now, divide each side of the equation by
a
+
b
to solve for
h
while keeping the equation balanced:

A
a

b
=
h
(
a

In 1 group there is 5 boys and 7girls
total students in 1 group: 7+5=12 students
now we know that there 12 students in 1 group. thus, we find how many groups of 12 are in 384384 students.
number of groups: 384384÷12=32032 groups
in each group we know we have 5 boys, so,
you multiply 5
32032×5=160160 boys
therefore, there is 160160 boys.
