Decrease 100 by 20 Percent

Decrease 100 by 20 percent

Answer: Result of decreasing 100 by 20 percent is 80, you do that by subtracting 20 (which is 20 percent of 100) to 100. Alternatively, we can say that 80 is equivalent to 80% of 100.

Solution for decreasing 100 by 20 percent:

n = decrease 100 by 20 percent

n = 100 - (20% of 100)

n = 100 - (\frac{20}{100} \times 100)

n = 100 - (\frac{2000}{100})

n = 100 - 20

n = 80

Now we have 100 decreased by 20 percent equals 80. Alternatively, we can express it as 80% of 100 = 80.

The step-by-step process for decreasing 100 by 20%:

The mathematical calculation for decreasing 100 by 20% can be broken down as follows:

Decrease 100 by 20 percent
Convert this into an equation: 100 - (20 / 100 * 100)
Simplify the equation further: 100 - (20 * 100)/100
Carry out the calculation: 100 - 2000/100 => 100 - 20
The final answer is: 80

Thus, we conclude that 80 is 100 decreased by 20%.

Explanation for decreasing 100 of 20 percent:

Step 1: Decrease 100 by 20%

We start by identifying the original number, which is 100, and the percentage decrease, which is 20%.

Step 2: Calculate 20% of 100

Next, we calculate 20% of 100. This is done by multiplying 100 by 20 and then dividing by 100, which gives us 20.

Step 3: Subtract the result from the original number

We then subtract this result (20) from our original number (100). This gives us the final result.

Step 4: 100 - 20

Subtracting 20 from 100 gives us 80.

Step 5: 80

Finally, we arrive at the answer: 80. Hence, we can definitively say that 100 decreased by 20% equals 80.
