- 25% of the annual profit of a company was invested in buying equipment. Total amount invested in buying the equipment was 100.000 dollars. What was the annual profit of the company? Rewrite: 25% of the Profit means 100,000 dollars => 25% × Profit = 100,000 dollars => Profit = 100,000 ÷ 25% dollars = 100,000 ÷ 25/100 dollars = 100,000 × 100/25 dollars = 100,000 × 4 dollars = 400,000 dollars;
- 20% of the students in the terminal year have enrolled into the swimming class. In total, 7 studens enrolled. How many students are in the terminal year? Rewrite: 20% of the students means 7 students => 20% × Total number of students = 7 => Total number of students = 7 ÷ 20% = 7 ÷ 20/100 = 7 × 100/20 = 7 × 5 = 35;
- In the last elections 49% of community memebrs voted for A Party, 32% for B Party, and the rest for C Party. 17,920 people voted for B Party. How many members has the community? Rewrite: 32% of the total community members means 17,920 people => 32% × Total number of community members = 17,920 => Total number of community members = 17,920 ÷ 32% people = 17,920 ÷ 32/100 people = 17,920 × 100/32 people = 17,920/32 × 100 = 560 × 100 people = 56,000 people.
