Final answer:
The pin on the ruler is 5/6 of an inch long, which means Maria is correct. The fractions 5/6 and 15/18 represent the same part of an inch, so both Maria and Ron are correct. The numerator and denominator of 5/6 can be multiplied by 3 to get 15/18.
Step-by-step explanation:
The pin shown on the ruler is alongside segments 1 to 5. Since the ruler is divided into six segments, we can conclude that the pin is 5/6 of an inch long. This means that Maria is correct.
On the other hand, Ron says that the pin is 15/18 of an inch long. To determine if this is true, we need to see if the fractions 5/6 and 15/18 represent the same part of an inch.
To compare 5/6 and 15/18, we can multiply the numerator and denominator of 5/6 by 3. This gives us 15/18. Therefore, the fractions are equivalent and both Maria and Ron are correct. So, the statements that are true are: Maria is correct, but Ron is not. Both fractions represent the same part of an inch. The numerator and denominator of Five-sixths can be multiplied by 3 to get Fifteen-eighteenths.
