Question

Convert the units of measure.
31 oz = ____ lb


Choose the best answer from the options below:
A 1 15 / 16
B 3 7 / 8
C 496
D 3 4 / 9

Answer 1

To convert ounces to pounds, you can use the conversion factor where 1 pound (lb) equals 16 ounces (oz).

To convert 31 ounces to pounds:
\[
\text{Pounds} = \frac{\text{Ounces}}{16} = \frac{31}{16}
\]

Calculating that gives:
\[
31 \div 16 = 1.9375
\]

Now, converting 1.9375 to a mixed number:
1.9375 can be expressed as 1 and the decimal part (0.9375) as a fraction.

To convert 0.9375 to a fraction:
0.9375 = \( \frac{9375}{10000} \)

Simplifying, we can write:
0.9375 = 15/16 (because both 9375 and 10000 can be divided by 625).

Therefore, 1.9375 in mixed number form is:
\[
1 \frac{15}{16}
\]

So, the answer is:
A. 1 15/16
