100 Divided By 31: Simple Math Explained!
Table of Contents :
To understand the division of 100 by 31, let's break down the process step by step. Division is a fundamental mathematical operation that involves splitting a number (the dividend) into equal parts, represented by another number (the divisor). In our case, we will be dividing 100 by 31.
What is Division? 📊
Division is the process of determining how many times one number can be subtracted from another. It’s one of the four primary arithmetic operations, alongside addition, subtraction, and multiplication.
Basic Terms in Division:
- Dividend: The number being divided (in this case, 100).
- Divisor: The number you are dividing by (in this case, 31).
- Quotient: The result of the division.
- Remainder: The amount left over after division, if the dividend is not evenly divisible by the divisor.
Performing the Division: 100 ÷ 31
Now, let's divide 100 by 31.
Step 1: Determine how many times 31 fits into 100.
31 goes into 100 three times, since:
- 31 × 3 = 93
Step 2: Calculate the remainder.
Now, subtract the product of 31 and 3 from 100:
- 100 - 93 = 7
Step 3: Result Interpretation
So, we can conclude that:
- Quotient: 3
- Remainder: 7
Putting this all together, we can write the division result as:
- 100 ÷ 31 = 3 R7 (3 with a remainder of 7)
Decimal Representation
If we want to express this division in decimal form, we can continue dividing.
Step 4: Convert to Decimal
To find the decimal form, you take the remainder (7) and add a decimal point to the dividend (100.0), making it 100.0.
- Bring down a zero to get 70.
- Now, see how many times 31 fits into 70, which is 2 times (31 × 2 = 62).
- Subtract 62 from 70 to get a new remainder of 8.
- Bring down another zero, making it 80.
- 31 fits into 80 two times (31 × 2 = 62).
- Again, subtract 62 from 80, which gives 18.
- Bring down another zero to get 180.
- 31 fits into 180 five times (31 × 5 = 155).
- Subtracting gives 25, then you bring down another zero to get 250.
- 31 fits into 250 eight times (31 × 8 = 248).
- This leaves a remainder of 2.
By repeating this process, you get a decimal representation:
- 100 ÷ 31 = 3.2258... (the division yields a repeating decimal).
