Answer:
Step-by-step explanation:
Explanation:
To solve this problem, you have to set up a proportion.
x
25
=
4
5
In this problem
x
is how any hours Noah spent on transmission.
To find
x
you have to cross multiply.
x
⋅
5
=
5
x
25
⋅
4
=
100
Now, you have to divide the product of the constants constants that don't have a variable (
24
and
4
) by
5
to find
x
.
100
÷
5
=
20
Our final answer for
x
is
20
.
Noah spent a total of
20
hours, or
4
5
of his
25
hours, working on transmission.
I hope this helps (:
