Given:

0.8 (Decimal form)

To find:

0.8 as fraction in simplest form

Solution:

N = 0.888... (Let N represent the number)

10N = 10(0.888...) (Multiply each side by 10 because one digit repeats)

10N = 0.888....

Subtract N from 10N to eliminate the repeating part, 0.888...

10N = 0.888....

-N = .888/9N = 8

9N/9 = 8/9 (Divide each side by 9)

N = 8/9

Therefore, 0.8 = 8/9

Answer:

0.8 = 8/9

Answer:

4/5

Step-by-step explanation:

Think of decimal numbers as being fractions of 1, it's a good place to start:

0.8=0.8/1

Most fractions need to have integers in the numerator, so we should first multiply our integer to remove all decimals. In this scenario, we multiply the top and bottom by 10:

=0.8/1×10/10

=8/10

Now, we reduce to the lowest whole number. Both the numerator and the denominator are divisible by 2, so let's divide both by 2. Another way of looking at this is multiplying by one half!

8/10 ×1/2/1/2 =4/5
