Question

Guided Practice

Directions: Describe each pair of ratio. Write P if it is a proportion and NP if
not proportion.
1.) 4:6 = 20:24
2.) 9: 6 = 36:24
3.) 2:5 = 15:45
4.) 3:5 = 6:10
5.) 40: 16 = 5:2​

Answer 1

1) NP

2) P

3) NP

4) P

5) P

Explanation:

re-write all the pairs into fractions

1.)
`(4)/(6) =(20)/(24)` {4 x 5 = 20} and {6 x 4 = 24} 5 ≠ 4

• (basically both the underlined numbers need to be the same)

I can do an explanation for each one if you need; just comment, cause I'll be on here for a while. Good luck! :D
