Finding 30% Of 400 With Decimal Method
To find 30% of 400, we first need to understand what percentage means. Percentage is a way of expressing a fraction or a portion of a whole as a fraction out of 100. So, 30% means 30 out of 100 or 30/100 as a fraction, which simplifies to 0.3 as a decimal.
Now, to find 30% of 400, we use the formula:
30% of 400 = (30/100) x 400
Here, we’re multiplying the decimal equivalent of 30% (0.3) by the number 400 to get the answer.
Simplifying this expression, we get:
30% of 400 = 0.3 x 400
Multiplying 0.3 and 400, we get:
30% of 400 = 120
Therefore, 30% of 400 is equal to 120.
