For the numeric part, you'll have to find the GCD of 15 and 25, which is 5. So, we can factor a 5 and we have
As for the literal part, you can factor because it's the power of s with the smallest denominator. So, we have

1 answer:
Answer:
<em>Riley has 72 tokens</em>
Step-by-step explanation:
<u>System of Equations </u>
We have two conditions for the tokens Riley and Erik have earned. Let's call x and y to the number of tokens of Riley and Erik respectively. The first condition states that
Solving for y
The second condition is that the ratio of the number of tokens that Riley had to the number of tokens that Erik has is 8 to 7. It's written as
Or equivalently
Replacing y from the first equation
Operating
Simplifying
Riley has 72 tokens

Answer:
Chi chi canhit a golf ball three times further than Rory.
Step-by-step explanation:
To compare the distance between the two golfers, we can set up a ratio:
Since the distance that Chi chi can hit the ball is 3:1 the distance that Rory can hit the ball, than Chi chi can hit the golf ball three times further. When reducing a ratio or fraction to lowest terms, you need to divide the numerator and the denominator by the same factor. Since 72 can be evenly divided by 24, we can divide both the numerator and the denominator by 24 to get 3:1.
