Convert 0.8 to a rational number
To convert 0.8 to a rational number, we need to express it as a fraction in the form of "a/b", where both "a" and "b" are integers.
Step 1: Let x = 0.8
Step 2: Multiply both sides of the equation by 10 to get rid of the decimal point:
10x = 10(0.8)
Step 3: Simplify:
10x = 8
Step 4: Divide both sides of the equation by 10:
(10x)/10 = 8/10
Step 5: Simplify further:
x = 8/10
So, 0.8 can be expressed as the rational number 8/10. We can reduce this fraction to its simplest form by dividing both numerator and denominator by their greatest common divisor:
8/10 = 4/5
Therefore, 0.8 is equal to the rational number 4/5.
To convert 0.8 to a rational number, we need to rewrite it as a fraction in the form of a/b, where a and b are integers.
Step 1: Let x equal 0.8.
x = 0.8
Step 2: Multiply both sides of the equation by 10 to move the decimal point one place to the right:
10x = 8
Step 3: Subtract x from both sides of the equation:
10x - x = 8 - 0.8
9x = 7.2
Step 4: Simplify the equation by dividing both sides by 9:
9x/9 = 7.2/9
x = 0.8/9
Therefore, the rational number equivalent to 0.8 is 0.8/9.
