Yes, they are equivalent.
To determine if two ratios are equivalent, we can simplify each ratio to its simplest form and then compare them.
The ratio 5/8 can be simplified by dividing both the numerator and the denominator by the greatest common divisor (GCD) of 5 and 8, which is 1. So, after simplifying, the ratio becomes 5/8.
The ratio 15/24 can be simplified by dividing both the numerator and the denominator by their GCD, which is 3. So, after simplifying, the ratio becomes 5/8.
Since both ratios simplify to 5/8, they are equivalent.

The unit rate of minutes per mile can be found by dividing the total minutes by the total miles.
In this case, Sam takes 56 minutes to run 8 miles.
So, the unit rate is: 56 minutes / 8 miles = 7 minutes/mile.
Therefore, the correct response is: 7 minutes/mile.
In this case, Sam takes 56 minutes to run 8 miles.
So, the unit rate is: 56 minutes / 8 miles = 7 minutes/mile.
Therefore, the correct response is: 7 minutes/mile.

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.
In this case, we have (3/5) ÷ (2/3).
To find the reciprocal of a fraction, we swap the numerator and denominator. So the reciprocal of 2/3 is 3/2.
Now, we can rewrite the division as multiplication: (3/5) * (3/2).
Multiplying the numerators, we get: 3 * 3 = 9.
Multiplying the denominators, we get: 5 * 2 = 10.
So, the result is: 9/10.
Therefore, the correct response is: 9 tenths.
In this case, we have (3/5) ÷ (2/3).
To find the reciprocal of a fraction, we swap the numerator and denominator. So the reciprocal of 2/3 is 3/2.

Multiplying the denominators, we get: 5 * 2 = 10.
So, the result is: 9/10.
Therefore, the correct response is: 9 tenths.

If it takes Ryan 2 hours to paint 1/5 of the wall, we can find out how long it will take him to paint the entire mural by multiplying the amount of time by 5 (since there are 5 equal parts in the whole wall).
So, 2 hours * 5 = 10 hours.
Therefore, the correct response is: 10 hours.
So, 2 hours * 5 = 10 hours.
Therefore, the correct response is: 10 hours.
