I agree with Guest's answer, but I wanted to show the work translating the sentence to an equation.

What percent of 8 is 1,280?

So, what percent for x, of for *(multiply), 8 for 8is for =(equals), 1280 for 1280

x * 8 = 1280

8x = 1280

$$\frac{8x}{8}=\frac{1280}{8}$$

x=160

x=160 * 100 = 16,000% D (multiply by 100 to turn into a percent)

16,000% * 8 = 1,280 (divide by 100 to turn into a decimal)

160 * 8 = 1280

The question is asking us to find a percentage, when multiplied by 8 equals 1280.

So, we can do: $$\frac{x}{100}*8=1280\longrightarrow \frac{8x}{100}=1280$$.

Taking 100 to the other side, we have:$$8x=1280*100\longrightarrow 8x=128000$$

Finishing this equation off, we get $$\frac{128000}{8}=\boxed{16,000}$$percent.
