1.17:1 is the ratio which forms a proportion of 12:7

7:12

A proportion is a statement built up of two ratios. A ratio is a comparison of two numbers. EX: Ratio- a:b or a/b EX: Proportion- 12/16=3/4 or 12:16=3:4

It depends on what that is. 312 : 624 is a ratio. 3 : 12 = 6 : 24 is a proportion.

A ratio is a comparison of two numbers. We generally separate the two numbers in the ratio with a colon (:). Suppose we want to write the ratio of 8 and 12.We can write this as 8:12 or as a fraction 8/12, and we say the ratio is eight to twelve while A proportion is an equation with a ratio on each side. It is a statement that two ratios are equal.3/4 = 6/8 is an example of a proportion.When one of the four numbers in a proportion is unknown, cross products may be used to find the unknown number. This is called solving the proportion. Question marks or letters are frequently used in place of the unknown number.

7:12 is a proportion, the total amount is 7+12=19, so the amounts as fractions are: 7/19 and 12/19

Yes

7:12 or 7 to 12

The Mr of Carbon monoxide (CO) is 28, since Ar of Carbon is 12 and Ar of Oxygen is 16. Then proportion by mass will be simple ratio of 12 to 16 giving 3:4

7 to 12.

3/5 is the same as 12/20 because they are equivalent fractions.

No, it is not equivalent. Think of it this way. If you had £12 and I had £5 then you would have money in the ratio of 12 to 5 compared to me. If you then only had £5 and I had £17 (which represents the new ratio of 5 to 17) you would not agree that this was equivalent as a proportion (you would rightly feel that you had lost out)!

There are many examples: 4:5, 24:30, 36:45, or 48:60. Was this helpful?

Yes.

9/12 = 3/4

5/6, possibly.
