3/5 is the same as 12/20 because they are equivalent fractions.
Well, it really is quite simple. The definition of proportion is finding two ratios that are equal. So for example, if the ratio of dogs to cats was 4:5 and there were 20 animals in total, and you needed to figure out how many dogs there are, then you would first have to figure out if it was a part to part or a part to whole. This is a part to part. Then you would write out your proportion- which in this case would be 4 = x For every 5 cats, there are 4 dogs, so you would find your answer. --- --- 5 20

7/35 = 5/x You have a proportion here. A proportion is a statement that two ratios are equal. The numbers that form a proportion are called the terms of proportion. There is a special relationship between the terms, called the cross products property. In the proportion that you have, 7 and x are called the extremes of the proportion, and 35 and 5 are called the means. In a proportion, the product of the means equals to the product of the extremes. So, 7/35 = 5/x (7)(x) = (35)(5) 7x = 175 7x/7 = 175/7 x = 25 Thus 7 is to 35 as 5 is to 25.
If you cross-multiply and you obtain an equality, then the proportion is true. Example: 2/3 = 20/30 ? cross-multiply; 2 x 30 = 3 x 20 ? 60 = 60 Since we have an equality, the proportion is true.
20% = 1/5
12/20 = 3/5
3/5 is the same as 12/20 because they are equivalent fractions.
No. 4/ 20 = 1/5, whichis not the same as 1/4
It is 9/20
Since you have multiplied 12 by 4 to get 48, you should multiply 5 by 4 to get 20.
3/4 and 20/30 does not make a proportion. 20/30 = 2/3 3/4 does not equal 2/3 so it is not a proportion.
46% of 20 is 9.2

5/10 = 1/2 write the proportion as ratios 5:10 = 1: 2 5/10 = 10/20 or 5:10 = 10:20 5/10 = 15/30 or 5:10 = 15:30
No. 20 is a number. 20% is a ratio or proportion meaning 20 out of every 100.
