21/25 as a Decimal

Answer

21/25 as a decimal can be written as 0.84. It is a terminating decimal, meaning it does not repeat infinitely.

Explanation

To convert 21/25 to a decimal, we will use the division method. Here, 21 is smaller than 25, so we will use the decimal method to convert it to 0.84. Let's see the step-by-step breakdown of the process:

Step 1: Identify the numerator and denominator because the numerator (21) will be taken as the dividend and the denominator (25) as the divisor.

Step 2: Since 21 is smaller than 25, it can't be divided directly, so we will take the help of decimals. We will add 0 to the dividend, making it 210, and add a decimal point in the quotient place.

Step 3: Now, divide 210 by 25. 25 goes into 210 eight times, because 25 × 8 = 200.

Step 4: Subtract 200 from 210 to get 10.

Step 5: Bring down another 0 in the dividend place, making it 100, and divide by 25. 25 goes into 100 four times, because 25 × 4 = 100.

Step 6: Subtract 100 from 100 to get 0 as the remainder. Since the remainder is 0, the process ends here, resulting in a terminating decimal.

The answer for 21/25 as a decimal is 0.84.
