Multiplying Decimals: 0.7 x 85
This article will explore how to multiply the decimal 0.7 by the whole number 85.
Understanding the Problem
When multiplying a decimal by a whole number, it's important to remember that the decimal represents a part of a whole. In this case, 0.7 represents seventenths. So, we are essentially finding seventenths of 85.
Multiplication Method
There are a few ways to approach this multiplication:
1. Standard Multiplication:

Ignore the decimal point for now and multiply 7 by 85.
7 x 85 = 595 
Count the number of decimal places in the decimal number (0.7 has one decimal place).

Place the decimal point in the product, starting from the right and moving it the same number of places as the decimal in the original number (one place).
Therefore, 0.7 x 85 = 59.5
2. Fraction Method:

Convert 0.7 to a fraction: 0.7 = 7/10

Multiply the fraction by the whole number: (7/10) * 85 = 595/10

Convert the fraction back to a decimal: 595/10 = 59.5
Conclusion
Both methods demonstrate that 0.7 multiplied by 85 equals 59.5. Understanding the concept of decimals as parts of a whole is key to performing these calculations accurately.
