How many ounces are in 2.55 pounds rounded to 3 significant digits?

There are 41.1 ounces in 2.55 pounds when rounded to 3 significant digits.

To convert pounds to ounces, we need to remember that there are 16 ounces in 1 pound.

So, to find the number of ounces in 2.55 pounds, we can multiply 2.55 by 16:

2.55 pounds * 16 ounces/pound ≈ 40.8 ounces

Rounding this quantity to 3 significant digits would give us:

40.8 ounces ≈ 41 ounces

To convert pounds to ounces, you can use the conversion factor of 16 ounces per pound.

Now, let's calculate the number of ounces in 2.55 pounds:

2.55 pounds * 16 ounces/pound = 40.8 ounces

To round to 3 significant digits, we start counting from the leftmost non-zero digit. In this case, it is 4.

Since there is no digit after the 4, we round the number:

If the digit following the last significant digit (zero in this case) is less than 5, we round down. If it is equal to or greater than 5, we round up.

In this case, the last significant digit is 4, and the following digit (zero) is less than 5. Therefore, we round 40.8 ounces down to 41 ounces.

So, there are 41 ounces (rounded to 3 significant digits) in 2.55 pounds.
