Question

What percent of 128.6 is 4?

Answer 1

3.11%

Explanation:

To solve percent problems, use the equation `a/b=p/100`. In this formula, a is the smaller number, b is the larger number, and p is the percent. In this case, a=4, and b=128.6. Plugging these values into the formula, we find:
`4/128.6=p/100`
Now we can solve the equation for p using cross-multiplication.
`4\times100=p\times128.6`
`400=p\times128.6`
`p=3.11`
So the answer is 3.11%
