Give an example of an equivalent ratio to 2:15 .(1 point)

An equivalent ratio to 2:15 would be 4:30.

To find an equivalent ratio to 2:15, you can multiply or divide both numbers by the same factor. In this case, let's multiply both numbers by 5:

2 * 5 = 10
15 * 5 = 75

Therefore, an equivalent ratio to 2:15 is 10:75.

To find an equivalent ratio to 2:15, you can multiply or divide both numbers by the same factor. This will give you a new ratio that is proportional to the original ratio.

Let's say we want to multiply both numbers by a factor of 3. We can calculate the equivalent ratio as follows:

2 * 3 = 6
15 * 3 = 45

Therefore, an equivalent ratio to 2:15 when multiplied by 3 is 6:45.

Similarly, if we want to divide both numbers by a factor of 5, we can calculate the equivalent ratio as follows:

2 / 5 = 0.4
15 / 5 = 3

So, an equivalent ratio to 2:15 when divided by 5 is 0.4:3.

Therefore, two examples of equivalent ratios to 2:15 are 6:45 and 0.4:3, obtained by multiplying and dividing both numbers by different factors, respectively.

Ruben and Claire are training to run a marathon in the spring. Ruben runs 16 miles over a 4-day period. Claire runs 12 miles over a 3-day period. Are they running at the same rate of speed? Respond "1" for yes or "2" for no.(1 point)

To determine if Ruben and Claire are running at the same rate of speed, we can compare their speeds based on the distances they covered over the same period of time.

Ruben runs 16 miles over 4 days, which means he runs at an average speed of 16 miles / 4 days = 4 miles per day.

Claire runs 12 miles over 3 days, which means she runs at an average speed of 12 miles / 3 days = 4 miles per day.

Since both Ruben and Claire are running at the same average speed of 4 miles per day, the answer is "1" for yes.
