which pair of ratios does NOT form a proportion?
A.3/ 5 24/40
B.30/10 15/3
C.9/14 3/4
D.7/12 14/24****
No.
Please do the calculations before you post another answer.
Actually two of your answer choices do not form a proportion. Check for a typo.
I need help not corrections on my mf typos
I'll give you an example.
D forms a proportion.
7/12 = 14/24
7 * 2 = 14
12 * 2 = 24
To determine which pair of ratios does not form a proportion, you need to check if the two ratios are equal to each other.
Let's check each option:
A. 3/5 and 24/40:
To determine if these two ratios are equal, we can simplify them.
3/5 cannot be simplified any further.
24/40 can be simplified to 3/5 since both 24 and 40 can be divided by 8.
Therefore, option A forms a proportion.
B. 30/10 and 15/3:
To determine if these two ratios are equal, we can simplify them.
30/10 can be simplified to 3/1 since both 30 and 10 can be divided by 10.
15/3 can be simplified to 5/1 since both 15 and 3 can be divided by 3.
Therefore, option B forms a proportion.
C. 9/14 and 3/4:
To determine if these two ratios are equal, we can simplify them.
9/14 cannot be simplified any further.
3/4 cannot be simplified any further.
Therefore, option C forms a proportion.
D. 7/12 and 14/24:
To determine if these two ratios are equal, we can simplify them.
7/12 cannot be simplified any further.
14/24 can be simplified to 7/12 since both 14 and 24 can be divided by 2.
Therefore, option D does not form a proportion.
So, the pair of ratios that does NOT form a proportion is option D: 7/12 and 14/24.
