What does 20% mean?

Before we dive in, let’s first define what we mean by 20%. In math, percentage is the expression of a proportion or a ratio in terms of hundredths. 20% is the same as 20/100, which can also be simplified to 1/5.

Step 1: Convert 150k into a decimal

To calculate 20% of 150k, we first need to convert 150k into decimal form. 1k is equivalent to 1,000, so 150k is the same as 150,000. To convert this number into decimal form, we simply divide it by 100. This gives us a decimal of 1500.

Step 2: Multiply the decimal by 20%

Now that we have our decimal, we can simply multiply it by 20%. To do this, we can convert 20% into decimal form by dividing it by 100. This gives us a decimal of 0.20. We can then multiply our previous decimal of 1500 by 0.20 to get the answer.

Breaking it down into smaller portions:

Now that we’ve gone through the calculations let’s break it down into smaller parts.

Step One: Converting 150k to decimal form

Here we convert our initial value, 150k, into decimal form. We do this by dividing 150k by 100, giving us a decimal value of 1500.

Step Two: Multiplying by 20%

Using the decimal value we just calculated, we now multiply it by 20%. To do this, we convert 20% into decimal form by dividing it by 100. This gives us a decimal of 0.20. Finally, we multiply 1500 by 0.20, which gives us the answer of 300.
