Math Problem Statement

Solve percentage-related mathematical problems, including finding parts, percentages, and whole numbers based on the user's image.

Solution

Let's go through each of the questions in the image. Here’s how we’ll approach them:

1. 2.5 is 17% of what number?

To solve this, use the formula: part=percent×whole\text{part} = \text{percent} \times \text{whole} Given that 2.5 is 17% of some number, we can express this as: 2.5=0.17×x2.5 = 0.17 \times x Solving for xx: x=2.50.17x = \frac{2.5}{0.17}

2. What is 40% of 600,000?

part=0.40×600,000\text{part} = 0.40 \times 600,000

3. What percent of 3 is 834,500?

percent=partwhole×100=834,5003×100\text{percent} = \frac{\text{part}}{\text{whole}} \times 100 = \frac{834,500}{3} \times 100

4. 388,500 is 33% of what number?

388,500=0.33×x388,500 = 0.33 \times x Solving for xx: x=388,5000.33x = \frac{388,500}{0.33}

5. What is 56% of 884,400?

part=0.56×884,400\text{part} = 0.56 \times 884,400

6. What percent of 56 is 224,000,000?

percent=224,000,00056×100\text{percent} = \frac{224,000,000}{56} \times 100

7. What is 18% of 538.50?

part=0.18×538.50\text{part} = 0.18 \times 538.50

8. What is 1.7% of 716,500?

part=0.017×716,500\text{part} = 0.017 \times 716,500

9. What percent of 58 is 675,000?

percent=675,00058×100\text{percent} = \frac{675,000}{58} \times 100

10. 10.889 is 1.3% of what number?

10.889=0.013×x10.889 = 0.013 \times x Solving for xx: x=10.8890.013x = \frac{10.889}{0.013}
