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 seven-tenths. So, we are essentially finding seven-tenths 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.
