Question: 1 / 400

How many inches of piping will you use if blueprints call for 8 sections of piping that are each 5 3/4 inches long?

44 inches

46 inches

To determine the total amount of piping needed, we start by calculating the total length of all sections of piping required as specified in the blueprints. Each section measures 5 3/4 inches, and there are 8 sections in total.

First, convert 5 3/4 inches to an improper fraction for easier calculations. The mixed number 5 3/4 can be converted as follows:

5 3/4 = (5 * 4 + 3) / 4 = 23/4 inches.

Now, we multiply this length by the number of sections:

Total length = Number of sections × Length of each section

Total length = 8 × (23/4).

When multiplying, we have:

8 × (23/4) = (8 × 23) / 4 = 184 / 4 = 46 inches.

Thus, the total length of piping needed is 46 inches. This matches the answer choice of 46 inches and confirms our calculations are accurate. This method emphasizes the importance of understanding fractions and multiplication in solving problems related to measurements.
