To convert the mixed number 5 4 into a decimal, we first need to understand how to handle mixed numbers. A mixed number consists of a whole number and a fraction. In this case, we have the whole number 5 and the fraction 4.
First, we convert the fraction 4 into a decimal. Since 4 is a whole number, we can write it as 4/1, which is equal to 4. This means we don’t actually have a fraction to convert, but rather just a whole number. So the next step is to combine this with the whole number part.
Now we simply add the whole number 5 to the decimal equivalent of the fraction 4. Thus, we have:
5 + 4 = 9
So, the decimal representation of the mixed number 5 4 is 9.
