Explanation:

First Question: Find 12.8% of 600

Step1: Convert percentage to decimal

To find a percentage of a number, we first convert the percentage to a decimal by dividing by 100. So, \( 12.8\% = \frac{12.8}{100} = 0.128 \)

Step2: Multiply by the number

Now, we multiply this decimal by 600. So, \( 0.128 \times 600 = 76.8 \)

Step1: Convert percentage to decimal

Convert \( 0.25\% \) to a decimal by dividing by 100. So, \( 0.25\% = \frac{0.25}{100} = 0.0025 \)

Step2: Multiply by the number

Multiply this decimal by 2000. So, \( 0.0025 \times 2000 = 5 \)
Wait, but the selected option in the image is 0.5, which is incorrect. The correct calculation gives 5. Let's recheck:
\( 0.25\% \) of 2000: \( \frac{0.25}{100} \times 2000 = 0.25 \times 20 = 5 \) (because \( \frac{2000}{100}=20 \))

Answer:

76.8 (corresponding to the option "76.8")
