What is 0.80 converted to a fraction? The answer should be given in simplest form.
A. 8
B. 4/5
C. 8/10
D. 8/1000
B. 4/5
To convert 0.80 to a fraction, we can write it as 80/100.
To simplify the fraction, we can divide the numerator and denominator by their greatest common factor, which is 10.
Dividing 80 by 10 gives us 8, and dividing 100 by 10 gives us 10.
So, the simplified fraction is 8/10.
However, we can further simplify this fraction. Both 8 and 10 are divisible by 2.
Dividing 8 by 2 gives us 4, and dividing 10 by 2 gives us 5.
Therefore, 8/10 simplifies to 4/5.
Hence, the answer is B. 4/5.
To convert a decimal to a fraction, follow these steps:
Step 1: Write down the decimal as a fraction with the decimal number as the numerator (top number) and the place value of the last digit as the denominator (bottom number).
In this case, the decimal is 0.80. The last digit is in the hundredths place, so the denominator will be 100.
So, 0.80 can be written as 80/100.
Step 2: Simplify the fraction to its simplest form.
To simplify the fraction, find the greatest common divisor (GCD) of the numerator and denominator, and divide both the numerator and denominator by their GCD.
In this case, the GCD of 80 and 100 is 20. By dividing both the numerator and denominator by 20, we get:
80 ÷ 20 = 4
100 ÷ 20 = 5
So, the fraction in its simplest form is 4/5.
Therefore, the answer is B. 4/5.
