Which of the following ratios are equivalent to 6.9? Choose all that apply.

To determine which ratios are equivalent to 6.9, we need to compare the given number with different ratios. A ratio represents a relationship between two quantities, so we can express 6.9 as a ratio by choosing any two numbers and dividing them.

Let's check the options:

Option 1: 6.9/1
Option 2: 13.8/2
Option 3: 27.6/4
Option 4: 34.5/5

To find out which ratios are equivalent to 6.9, we divide the numerator by the denominator for each option:

Option 1: 6.9/1 = 6.9
Option 2: 13.8/2 = 6.9
Option 3: 27.6/4 = 6.9
Option 4: 34.5/5 = 6.9

By comparing the results, we can see that all the ratios are equivalent to 6.9. Therefore, you should choose all of the options: Option 1, Option 2, Option 3, and Option 4.

To determine which ratios are equivalent to 6.9, we need to divide 6.9 by different numbers and check for equivalent ratios. Here are the possible options to check:

1. 6.9/1 = 6.9
2. 13.8/2 = 6.9
3. 20.7/3 = 6.9
4. 34.5/5 = 6.9
5. 69/10 = 6.9

From the options above, the ratios 6.9/1, 20.7/3, and 69/10 are all equivalent to 6.9.

A. 69:10

B. 69:1
C. 6.9:1
D. 13.8:2
