The decimal representation of the fraction $4 \frac{27}{125}$ is $4.216$.
Steps to Solve
- Convert the Mixed Number to an Improper Fraction
To convert the mixed number $4 \frac{27}{125}$ into an improper fraction, we can use the formula: $$ \text{Improper Fraction} = \text{Whole Number} \times \text{Denominator} + \text{Numerator} $$
In this case: $$ \text{Improper Fraction} = 4 \times 125 + 27 = 500 + 27 = 527 $$
So, the improper fraction form is: $$ \frac{527}{125} $$
- Perform the Division to Convert to Decimal
Now we need to convert the improper fraction $\frac{527}{125}$ into decimal form by dividing the numerator by the denominator: $$ 527 \div 125 $$
This division can be carried out as follows:
- 125 goes into 527 four times (since $4 \times 125 = 500$)
- Subtract $500$ from $527$ to get the remainder: $527 - 500 = 27$.
- Now, we can append a decimal and a zero to the remainder to continue the division: $270 \div 125$
125 goes into 270 two times (since $2 \times 125 = 250$)
- Subtract $250$ from $270$: $270 - 250 = 20$.
- Append another zero to make it $200 \div 125$.
125 goes into 200 once (since $1 \times 125 = 125$)
- Subtract $125$ from $200$: $200 - 125 = 75$.
- Append another zero to make it $750 \div 125$.
125 goes into 750 six times (since $6 \times 125 = 750$)
- The division ends here, and there is no remainder.
So $527 \div 125 = 4.216$.
Now we combine the results from the division to get the complete decimal.
- Combining the Results
From the steps of our division, we have: $$ 4 + 0.216 = 4.216 $$
Thus, the decimal representation of the mixed number $4 \frac{27}{125}$ is $4.216$.
The decimal representation of the fraction $4 \frac{27}{125}$ is $4.216$.
