How do you write 0.4 as a fraction?

Answer 1

Answer:

Step-by-Step Solution

0.4 = 2/5 as a fraction

To convert the decimal 0.4 to a fraction, just follow these steps:

Step 1: Write down the number as a fraction of one:

0.4 = 0.41

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,

0.41 = (0.4 × 10)(1 × 10) = 410.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(4,10) = 2. So,

(4÷2)(10÷2) = 2/5 when reduced to the simplest form.
