Answer 1

Answer:

The answer is 8!

Step-by-step explanation:

75% is 3/4 of 100 so you take 32÷4 and get 8, hope this helps:)

Answer 2

• 75% of 32 students are interested in Mathematics.
• Therefore, number of students who are interested in Mathematics
• $= 75\% \: \: of \: \: 32 \\ = \frac{75}{100} \times 32 \\ = \frac{3}{4} \times 32 \\ = 3 \times 8 \\ = 24$
• So, number of students interested in Mathematics is 24.
• Therefore, number of students who are not interested in Mathematics = 32 - 24 = 8
• So, 8 students are not interested in Mathematics.

Alternative method:

• Percentage of students who are interested in Mathematics = 75%
• Then, percentage of students who are not interested in Mathematics = (100 - 75)% = 25%
• Therefore, number of students who are not interested in Mathematics
• $= 25\% \: \: of \: \: 32 \\ = \frac{25}{100} \times 32 \\ = \frac{1}{4} \times 32 \\ = 1 \times 8 \\ = 8$

Answer:

8
