Equivalent display equivalent part to part ratios in the two column table cups of flour cups of sugar 2:1

14:
:9
20:10

28:14

To find the equivalent part-to-part ratios for the given table, let's first determine the missing values and then calculate the ratios between the two columns.

Here's the given two-column table:

Cups of Flour | Cups of Sugar
2 | 1
14 | ?
? | 9
20 | 10

To determine the missing values, we will set up proportions:

1) For the missing value in the second row (14: ?), we can set up the following proportion:

2/1 = 14/?

Cross-multiplying, we get:

2 * ? = 14 * 1
? = (14 * 1) / 2
? = 7

So, the missing value in the second row is 7.

2) For the missing value in the third row (? : 9), we can set up the following proportion:

2/1 = ?/9

Cross-multiplying, we get:

2 * 9 = ? * 1
? = (2 * 9) / 1
? = 18

So, the missing value in the third row is 18.

Now, let's calculate the equivalent part-to-part ratios:

1) The ratio for the first row (2:1) remains the same.

2) For the second row (14:7), we can simplify it by dividing both numbers by 7:

14/7: 7/7
2:1

So, the ratio for the second row is also 2:1.

3) For the third row (18:9), we can simplify it by dividing both numbers by 9:

18/9: 9/9
2:1

So, the ratio for the third row is also 2:1.

4) The ratio for the fourth row (20:10) is already simplified.

Therefore, the equivalent part-to-part ratios for the given table are:

2:1
2:1
2:1
20:10

To find the equivalent part-to-part ratios, you need to determine the common ratio between the initial ratios.

1. Start with the given ratio in the two-column table: cups of flour : cups of sugar = 2:1.

2. Multiply both sides of the ratio by the same number to maintain the ratio. For example, you can multiply the ratio by 7 to get a common denominator.

2 x 7: 1 x 7 = 14: 7

3. Repeat the same process for the second ratio: 20:10.

Multiply both sides by 2 to find the common ratio.

20 x 2: 10 x 2 = 40: 20

Simplify the ratio by dividing both numbers by their greatest common factor, which is 20.

40 ÷ 20: 20 ÷ 20 = 2: 1

So, the equivalent part-to-part ratios are:

2:1
14:7
and
2:1
40:20
