Verified step by step guidance

Start by understanding the conversion factors provided: 1 quart = 2 pints, 1 pint = 2 cups, and 1 cup = 8 fluid ounces.

Determine how many fluid ounces are in one quart. Since 1 quart = 2 pints, and 1 pint = 2 cups, and 1 cup = 8 fluid ounces, calculate the total fluid ounces in a quart using the formula: 1 quart = 2 pints * 2 cups/pint * 8 fluid ounces/cup.

Calculate the total fluid ounces in a quart: 1 quart = 2 * 2 * 8 fluid ounces.

Now, use the conversion factor to convert 160 fluid ounces to quarts. Divide the total fluid ounces (160) by the number of fluid ounces in one quart.

Perform the division to find the number of quarts: 160 fluid ounces / (fluid ounces per quart). This will give you the number of quarts of blood in the average human body.
