Answer for screen readers
The result of dividing 121 by 8 is $15.125$.
Steps to Solve
-
Perform the Division To find the result of dividing 121 by 8, we set up the division as follows: $$ \frac{121}{8} $$
-
Calculate the Quotient When we divide, we need to find how many times 8 fits into 121. In this case:
- 8 goes into 121 a total of 15 times (since $8 \times 15 = 120$).
-
Calculate the Remainder Now, we need to find the remainder after multiplying. We compute: $$ 121 - 120 = 1 $$ So, the remainder is 1.
-
Express the Result The result of the division can be expressed as: $$ 15 \text{ R } 1 $$ This indicates that 121 divided by 8 gives us a quotient of 15 with a remainder of 1.
-
Convert to Decimal (if needed) To express the result as a decimal, we can continue the division by adding a decimal point and zeros:
- 8 goes into 10 (from the remainder of 1) 1 time (since $8 \times 1 = 8$).
- This leaves a new remainder of 2. We can carry down a zero to get 20.
- 8 goes into 20 a total of 2 times ($8 \times 2 = 16$), leaving a remainder of 4.
- Continuing this gives us $15.125$.
The result of dividing 121 by 8 is $15.125$.
More Information
The division of 121 by 8 is an example of basic arithmetic, which often appears in everyday calculations. The result can be expressed as a mixed number ($15 \frac{1}{8}$) or a decimal ($15.125$), showing the flexibility in expressing fractions.
Tips
- Forgetting to account for remainders when dividing.
- Not converting the remainder into a decimal properly, which can lead to an inaccurate result.
- Confusing the order of results (quotient vs. remainder) when presenting answers.
