Answer: 280 is 70% of 400
Step-by-Step Solution
Step 1 Understand the Problem

We need to find what percentage 280 is of 400.


Part (the amount we have): 280

Whole (the total): 400


We're asking: "280 out of 400 is how many percent?"

Step 2 Set Up the Formula

To find what percent one number is of another, we use:


Percentage = (Part ÷ Whole) × 100


This gives us the part as a fraction of the whole, then converts to a percentage.

Step 3 Calculate the Percentage

Step 1: Divide the part by the whole:

280 ÷ 400 = 0.7

Step 2: Multiply by 100 to convert to percent:

0.7 × 100 = 70%

Step 4 Interpret the Result

280 is 70% of 400.


This means if you had 400 items and took 280 of them,

you would have 70% of the total.
