Answer:
To find out how many cups of water will fill an empty glass of the same size, we can use the information given.
Oscar poured 3/4 cup of water into an empty glass, and it filled 5/8 of the glass.
To determine the size of the glass, we need to find the common denominator of 4 and 8, which is 8.
Since 3/4 cup of water filled 5/8 of the glass, we can say that 3/4 is equal to 5/8.
To make the denominators the same, we need to multiply the numerator and denominator of 3/4 by 2, resulting in 6/8.
So, 6/8 cup of water filled the glass completely.
Now, if the glass is empty, we need to find how many cups of water will fill it.
Since 6/8 cup of water filled the glass completely, we can conclude that 6/8 cup of water is the capacity of the glass.
Therefore, an empty glass of the same size will be filled with 6/8 cup of water.
