21/20 as a Decimal

Answer

21/20 in decimals can be written as 1.05. It is a terminating decimal, showing it will end after a few digits.

Explanation

To get 21/20 in decimal, we will use the division method. Here, 21 is larger than 20, so it will result in a whole number with a decimal. 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 (20) will be taken as the divisor.

Step 2: Perform the division of 21 by 20.

Step 3: 21 divided by 20 gives 1 as the whole number part since 20 fits into 21 once.

Step 4: Subtract 20 from 21 to get a remainder of 1.

Step 5: Bring down a 0 to make it 10, then divide 10 by 20, which gives 0.5.

Step 6: The division ends here as the remainder becomes 0, making it a terminating decimal.

Therefore, the answer for 21/20 as a decimal is 1.05.
