To calculate 699 x 1.075, you can follow these simple steps:
Step-by-Step Calculation
First, understand that multiplying by 1.075 is the same as multiplying by 1 and then adding 7.5% of the original number. The calculation can be broken down as follows:
Breaking Down the Calculation
1. Multiply 699 by 1 (which doesn’t change the value): 699 * 1 = 699.
2. Calculate 7.5% of 699: 7.5% of 699 = (7.5⁄100) * 699.
To find 7.5% of 699, convert the percentage to a decimal by dividing by 100: 7.5⁄100 = 0.075.
Then, multiply 699 by 0.075: 699 * 0.075 = 52.425.
3. Add the result of step 2 to the result of step 1: 699 + 52.425 = 751.425.
| Calculation Step | Result |
|---|---|
| Multiply 699 by 1 | 699 |
| Calculate 7.5% of 699 | 52.425 |
| Add the two results together | 751.425 |
The exact result of 699 x 1.075 is 751.425. This method demonstrates how to break down the multiplication into simpler steps for easier calculation.
