Convert 0.8 to a rational number.
To convert 0.8 to a rational number, we can express it as a fraction.
Since 0.8 can be written as 8/10, we can simplify it by dividing the numerator and denominator by their greatest common divisor. In this case, 8 is divisible by 2 and 10 is divisible by 2, so the simplified fraction is:
8/10 = 4/5
Therefore, 0.8 can be expressed as the rational number 4/5.
To convert 0.8 to a rational number, we need to express it as a fraction.
Step 1: Write 0.8 as a fraction with a denominator of 1.
0.8 = 0.8/1
Step 2: Multiply both the numerator and denominator by 10 to remove the decimal point.
0.8/1 x 10/10 = 8/10
Step 3: Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor. In this case, the greatest common divisor of 8 and 10 is 2.
8/10 ÷ 2/2 = 4/5
Therefore, 0.8 as a rational number is 4/5.
