I already asked this question but I don't think anyone saw it.
Which ratios can form a proportion?
A. 20\25 , 14\21
B. 10\23 , 18\7
C. 5\45 , 4\36
D. 5\4 , 4\5
Any help would be awesome :)
Simplify each fraction
20/25 = 4/5
14/21 = 2/3
Nope -- they don't form a proportion
If you post your answer, I'll check it for you.
