A vet tech uses several measurements of solution for urinary analysis tests. What is the total volume used if the amounts are ½ oz, ¾ oz, and 5/8 oz?

To find the total volume of the solutions used for urinary analysis tests, we need to add the three given measurements: ½ oz, ¾ oz, and 5/8 oz.

First, it's helpful to convert each measurement into a fraction form that is easy to add. The denominators can be standardized to 8 for easier addition:

1. ½ oz can be expressed as 4/8 oz.
2. ¾ oz can be expressed as 6/8 oz.
3. 5/8 oz remains as it is.

Now we add these fractions together:

• 4/8 oz (from ½ oz)
• 6/8 oz (from ¾ oz)
• 5/8 oz

Adding these gives us:

4/8 + 6/8 + 5/8 = (4 + 6 + 5)/8 = 15/8.

The fraction 15/8 can be converted into a mixed number. Since 15 divided by 8 equals 1 with a remainder of 7, we can express this as:

1 7/8 oz.

Thus, the total volume used for the urinary analysis tests is indeed 1 7/8 oz,
