April scored 81% on the test meaning she earned 81% of the possible points on the test. There were 360 possible points on the test so she earned 360 x 0.81 = 292 points. Each question is worth 4 points so she got \( \frac{292}{4} \) = 73 questions right.

You have 12 out of the total of 300 raffle tickets sold so you have a (\( \frac{12}{300} \)) x 100 = \( \frac{12 \times 100}{300} \) = \( \frac{1200}{300} \) = 4% chance to win the raffle.

If the tiger has consumed 81 pounds of food in 9 days that's \( \frac{81}{9} \) = 9 pounds of food per day. The tiger needs to consume 108 - 81 = 27 more pounds of food to reach 108 pounds total. At 9 pounds of food per day that's \( \frac{27}{9} \) = 3 more days.

The number of students taking German or Spanish is 15 + 7 = 22. Of that group of 22, 7 are taking both languages so they've been counted twice (once in the German group and once in the Spanish group). Subtracting them out leaves 22 - 7 = 15 who are taking at least one language. 24 - 15 = 9 students who are not taking either language.

To multiply fractions, multiply the numerators together and then multiply the denominators together:

\( \frac{1}{9} \) x \( \frac{4}{7} \) = \( \frac{1 x 4}{9 x 7} \) = \( \frac{4}{63} \) = \(\frac{4}{63}\)
