What is 0.7 as a rational number in the form a b
To express 0.7 as a rational number in the form a b, we need to first understand the meaning of a rational number and the form a b.
A rational number is a number that can be expressed as the ratio of two integers (a fraction), where the denominator is not zero. The form a b represents the fraction, where "a" is the numerator and "b" is the denominator.
To convert 0.7 into a rational number, we can follow these steps:
1. Write down the number 0.7.
2. Since there is a decimal point, we can assume 0.7 can be written as 7/10 because 0.7 is equivalent to 7 divided by 10.
(Note: We moved the decimal point one place to the right to get the numerator 7 and the denominator remains as 10).
3. Therefore, 0.7 as a rational number in the form a b is 7/10.
