(10) The school orchestra has 15 woodwinds, 30 brass instruments, 25 strings and 30 percussionists. Select the portion of the instruments that are strings. Mark all that apply. A. \( \square 250 \% \) B. C. \( 25: 1 \) 0.25 D. \( \square \frac{1}{25} \)

To find the portion of string instruments in the orchestra, we first need to determine the total number of instruments. Adding them up gives us: 15 (woodwinds) + 30 (brass) + 25 (strings) + 30 (percussion) = 100 total instruments. Now, the portion of string instruments can be calculated as follows: Number of string instruments: 25 Total instruments: 100 Portion of string instruments = \( \frac{25}{100} \) = 0.25 (which corresponds to option C). So, the correct answers are: C. \( 0.25 \) And that’s your string instrument portion (25 out of 100). Now, let’s jazz up our knowledge a bit! Each instrument brings its unique flair to the orchestra, and among strings, you’ll find violins, cellos, and more, making it a splendid ensemble! Think of it as a delicious recipe where each ingredient enhances the final dish. When talking about portions, remember that decimals and fractions can express the same idea in different ways. For instance, \( \frac{1}{4} \) and 0.25 are equivalent, just dressed in different clothes! Always double-check to ensure clarity in communication!
