Converting 0.78 to a Fraction in 5 Easy Steps

Converting a decimal number to a fraction can seem daunting, but it's a straightforward process that can be completed in just a few steps. In this article, we'll walk you through the process of converting 0.78 to a fraction in 5 easy steps.

Step 1: Identify the Decimal Number

The first step is to identify the decimal number you want to convert to a fraction. In this case, we're working with the decimal number 0.78.

Step 2: Determine the Place Value

Next, we need to determine the place value of the last digit in the decimal number. In this case, the last digit is 8, which is in the hundredths place.

Step 3: Write the Decimal as a Fraction

Now, we can write the decimal number as a fraction by placing the digits after the decimal point over the place value. In this case, we would write:

0.78 = 78/100

Step 4: Simplify the Fraction

The next step is to simplify the fraction by dividing both the numerator and denominator by the greatest common divisor (GCD). In this case, the GCD of 78 and 100 is 2. So, we would divide both numbers by 2 to get:

78 ÷ 2 = 39 100 ÷ 2 = 50

So, the simplified fraction is:

0.78 = 39/50

Step 5: Check the Answer

The final step is to check our answer to make sure it's correct. We can do this by converting the fraction back to a decimal number and checking if it matches the original decimal number. In this case, we can convert the fraction 39/50 back to a decimal number by dividing the numerator by the denominator:

39 ÷ 50 = 0.78

This matches the original decimal number, so we know our answer is correct.
