Which equation is true? Explain your answer.
Liula [17]

Answer:

<h2>12/36</h2>

Step-by-step explanation:

1. Find if all of the fractions are equal to the other fraction next to them.

First, let's go with the denominator of all.

6/8 = 4/3

First of all, we can easily say that this is not right, since the fact that, 6 is less than 8, and 4 is greater than 3. That's just signaling that this can't be the answer.

3/5 = 8/10

10/5=2

8/3=??? (doesn't go into 8)

So, this one is also wrong

12/16 = 36/48

48/16=3

36/12=3

<h2>So hence, the last one or 12/16=36/48 is RIGHT.</h2>

James decides to walk from school to the park tp play ball. The park is only 0.5 mile from the school. He leaves school at 3:15
aleksley [76]

Answer: 0.05\ \frac{mi}{min}

Step-by-step explanation:

For this exercise you need to remember the following formula:

V=\frac{d}{t}

Where "V" is the speed, "d" is the distance and "t" is time.

In this case, according to the information given in the exercise, you know that:

- James leaves his school at 3:15 and arrives at the park at 3:25. Then, you can identify that the time it takes him to go from his school to the park is:

t=10\ min

- The park is 0.5 miles from James' school. Therefore, you can identify that "d" is:

d=0.5\ mi

So, knowing those values, you can substitute them into the formula:

V=\frac{0.5\ mi}{10\ min}

Finally, evaluating, you get the following result:

V=0.05\ \frac{mi}{min}
