Answer:
All of the above.
Step-by-step explanation:
I think the correct answer is all of the above.
10/60 = 15/x Cross multiply
10x = 60 * 15 Combine the right
10x= 900 Divide by 10
x = 90
So 15 becomes 6 times larger or 90
=====
10/60 = 20/x Cross multiply
10x = 60 * 20 Combine the right
10x = 1200 Divide by 10
x = 120
$$$$$$$$$$$
The time let 15 go to 60
15/60 = 10 / x
15x = 600
x = 40
==============
15/60 = 20/x
15x =60 * 20
15x = 1200
x = 80
$$$$$$$$$$$
This time the 20 will go to 60
I will let you figure out how the proportion works.
10 will go to 30
15 will go to 45
$$$$$$$$$$$
Answer: all of the above are correct.
