Determine which ratio forms a proportion with 9/5 by finding a common multiplier?

9/5

The numerator is almost double the denominator. That eliminates three of the answers.

54/30 54/9 = 6; 6 * 5 = 30. Yep; this is right.

45/50
45/40
90/20

You can use the same reasoning on the other two problems.

Um, can someone help explain out the answer to this question:

7. Determine which ratio forms a proportion with 8/3 by finding a common multiplier. (1 point)
A. 24/15
B. 16/9
C. 28/9
D. 72/27

I believe that the answer is maybe D?

um, ya, can someone help Ready as I'll ever be, i am stuck on the same question.

14/35 = 2/5

I have no reason to lie

Look at my name

72/27

WHAT IS THE ANSWER?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

To find a ratio that forms a proportion with a given ratio, you can either find a common multiplier or use cross products.

To find a common multiplier, you need to multiply both the numerator and denominator of the given ratio by the same number. By doing so, the resulting ratio will be equivalent to the given ratio.

Let's determine which ratio forms a proportion with 9/5 by finding a common multiplier:

First, we multiply 9/5 by a common multiplier:

Ratio 1: 54/30 = 9/5 * 6/6 = 54/30

Ratio 2: 45/50 = 9/5 * 5/5 = 45/50

Ratio 3: 45/40 = 9/5 * 9/9 = 45/40

Ratio 4: 90/20 = 9/5 * 10/10 = 90/20

By comparing the resulting ratios with the given ratio (9/5), we can see that Ratio 1 (54/30) forms a proportion with 9/5.

Now, let's determine which ratio forms a proportion with 12/7 using cross products:

Using cross products, we can compare the products of the diagonals of two ratios. If the products are equal, the ratios form a proportion.

Let's calculate the cross products for each ratio:

Ratio 1: 60/35 = 12/7 * 5/5 = 60/35

Ratio 2: 24/10 = 12/7 * 2/2 = 24/10

Ratio 3: 36/14 = 12/7 * 3/3 = 36/14

Ratio 4: 18/14 = 12/7 * 2/2 = 18/14

By comparing the cross products with the given ratio (12/7), we can see that Ratio 1 (60/35) forms a proportion with 12/7.

Lastly, let's find the ratio that can form a proportion:

To determine whether two ratios form a proportion, we need to compare their cross products. If the cross products are equal, the two ratios form a proportion.

Let's calculate the cross products for each pair of ratios:

Cross product 1: 20/25 * 21/14 = 60/70

Cross product 2: 10/23 * 18/7 = 180/161

Cross product 3: 5/45 * 4/36 = 20/1620

Cross product 4: 5/4 * 4/5 = 20/20

By comparing the cross products, we can see that only Cross product 4 (20/20) is equal, which means that the ratios 5/4 and 4/5 form a proportion.
