Question

8 is what percent of 5? Plz help

Answer 1

8 is 160% of 5.

Explanation:

Let's see if we can "translate" this sentence into numbers that we can work with. The 8 is going to stay the same because it's already a number. "Is" indicates an equal sign. "What percent" is something we don't know, so let's go ahead and call it `\fracx 100` because we know it's a percent. And lastly, 5 is going to stay the same because it is also already a number.

That gives us the following equation:
`8 = \fracx 100 \times 5`.

To solve for `x`, we divide both sides by 5 so we can start to isolate `x`:
`\frac 8 5 = \fracx 100`.

As a decimal, `\frac8 5` is `1.6`, so we can write this:
`1.6 = \fracx 100`.

To finish isolating `x`, we multiply both sides by `100`:
`160 = x`.

And there you have it; 8 is 160% of 5.
