Answer :

To determine what percent 48 is of 400, you can follow these steps:

1. Identify the "part" and the "whole":
- The "part" here is 48.
- The "whole" (or total) is 400.

2. Set up the fraction:
- You need to find the fraction of the part (48) relative to the whole (400).

3. Convert the fraction to a percentage:
- A percentage is a fraction out of 100, so you need to multiply your fraction by 100 to convert it.

4. Calculate the fraction and then the percentage:
- First, divide the part by the whole: [tex]\( \frac{48}{400} \)[/tex].
- Then, multiply the result by 100 to convert it to a percentage.

5. Determine the result:
- [tex]\( \frac{48}{400} = 0.12 \)[/tex].
- Multiply by 100 to get the percentage: [tex]\( 0.12 \times 100 = 12 \)[/tex].

Thus, 48 is 12 percent of 400.
