To find the combined measurement of the two pieces of wood, you need to add the two fractions together.

You have 3/16 inch and 5/16 inch. When adding fractions with the same denominator, you keep the denominator the same and simply add the numerators:

3/16 + 5/16 = (3 + 5)/16 = 8/16.

The next step is to simplify the fraction. The fraction 8/16 can be simplified by dividing both the numerator and the denominator by the greatest common divisor, which is 8 in this case. So,

8 ÷ 8 / 16 ÷ 8 = 1/2.

This means that the combined measurement of the two pieces of wood is 1/2 inch.

In this context, the other options do not represent the sum correctly. 5/16 inches is one of the original measurements and cannot be the combined total. 1/4 inches is smaller than both pieces and thus also cannot be correct. 3/8 inches is less than the combined total of 1/2 inch and is therefore not accurate either. Thus, the measurement in its lowest form is 1/2 inches.
