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.
