What is Percentage?

Percentage is a way to express a value as a fraction of 100. It is used to represent a part of a whole as a proportion of 100. In other words, it is a number that represents a part of a whole as a fraction of 100. For example, 25% is equal to 25 out of 100, or 1/4.

Calculating 68 Percent of 150

To find 68 percent of 150, we need to multiply 150 by 0.68. This is because 68 percent is equal to 68/100, which is the same as 0.68.

Step 1: Convert 68 Percent to a Decimal

To convert 68 percent to a decimal, we divide 68 by 100. This gives us 0.68.

Step 2: Multiply 150 by 0.68

Now that we have the decimal equivalent of 68 percent, we can multiply 150 by 0.68.

# Calculate 68 percent of 150
result = 150 * 0.68
print(result)

Step 3: Calculate the Result

When we multiply 150 by 0.68, we get:

# Calculate 68 percent of 150
result = 150 * 0.68
print(result)
102

Conclusion

Therefore, 68 percent of 150 is equal to 102.
