Answer: 0.7 as a fraction is 7/10​.

To convert the decimal 0.7 to a fraction, you need to understand the place value of the decimal. In 0.7, the 7 is in the tenth-place, which means 0.7 can be expressed as 7 tenths. As a fraction, this is written as 7/10.

The conversion process is straightforward:

1. Write down the number as a fraction of one (0.7 = 0.7/ 1).
2. Multiply both the top and bottom of the fraction by 10 to get rid of the decimal point : (0.7×10) ÷ (1×10) = 7/ 10.

This type of conversion is a fundamental aspect of understanding numbers in mathematics. Decimals and fractions are two different ways to represent the same concept: parts of a whole. Converting between these forms is a common task in various fields, including mathematics, science, and engineering. Understanding how to make these conversions is essential for problem-solving and for interpreting data accurately.
