What is 3/7 as a Decimal?

3/7 as a decimal is 0.428571. To convert a fraction to a decimal, we divide the numerator (3) by the denominator (7).

Key Facts

  1. The decimal representation of 3/7 is 0.428571.
  2. To convert a fraction to a decimal, divide the numerator (3) by the denominator (7).
  3. The long division method is commonly used to convert fractions to decimals.
  4. In the long division method, the digits are divided one by one until the remainder is zero.
  5. If the division does not reach a remainder of zero and repeats the same remainders, the resulting decimal is called a recurring or repeating decimal.
  6. In the case of 3/7, the decimal digits 428571 repeat indefinitely, so it is a recurring decimal.
  7. Recurring decimals are often denoted by placing a bar over the repeating digits, so 3/7 can be written as 0.428571 with a bar over the digits 428571.

Long Division Method

The long division method is commonly used to convert fractions to decimals. In the long division method, the digits are divided one by one until the remainder is zero.

Step 1: Set up the Division Problem

3 ÷ 7 = 0.428571

Step 2: Divide the Numerator by the Denominator

3 ÷ 7 = 0.42

Step 3: Bring Down the Remainder

3 ÷ 7 = 0.428

Step 4: Multiply the Remainder by 10 and Divide by the Denominator

28 ÷ 7 = 4

Step 5: Bring Down the Remainder

28 ÷ 7 = 4.05

Step 6: Multiply the Remainder by 10 and Divide by the Denominator

5 ÷ 7 = 0.71

Step 7: Bring Down the Remainder

5 ÷ 7 = 0.714

Step 8: Multiply the Remainder by 10 and Divide by the Denominator

14 ÷ 7 = 2

Step 9: Bring Down the Remainder

14 ÷ 7 = 2.000

Step 10: Multiply the Remainder by 10 and Divide by the Denominator

0 ÷ 7 = 0

Step 11: Stop Dividing

The remainder is 0, so we stop dividing.

Recurring Decimals

In the case of 3/7, the decimal digits 428571 repeat indefinitely, so it is a recurring decimal. Recurring decimals are often denoted by placing a bar over the repeating digits, so 3/7 can be written as 0.428571 with a bar over the digits 428571.

Conclusion

3/7 as a decimal is 0.428571. This can be found using the long division method. The decimal is recurring, meaning that the digits 428571 repeat indefinitely.
