Convert Fraction to Decimal: Solving 7/2

Q: Why do I divide the top number by the bottom number?

Division tells you how many whole groups you can make! When you have $ \frac{7}{2} $, you're asking 'how many groups of 2 can I make from 7?' The answer is 3 complete groups with 1 left over.

Q: What if there's no remainder?

If there's no remainder, you get a whole number! For example, $ \frac{8}{2} = 4 $ exactly, so the answer is just 4, not a mixed number.

Q: Can I convert this to a decimal instead?

Absolutely! $ \frac{7}{2} = 3.5 $ because $ 7 \div 2 = 3.5 $. Mixed numbers and decimals are just different ways to show the same value.

Q: Why can't I just guess the answer?

Math requires exact precision! Even small errors like writing $ 2\frac{1}{7} $ instead of $ 3\frac{1}{2} $ give completely wrong values. Following the division steps guarantees the right answer.

Understand the problem

Solve the following:

$\frac{7}{2}=$

Step-by-step solution

To convert the improper fraction $\frac{7}{2}$ into a mixed number, we will perform the following steps:

Step 1: Divide the numerator by the denominator. Here, divide 7 by 2.
Step 2: Calculate the quotient and the remainder from the division.
Step 3: Express the result as a mixed number, with the quotient as the whole number and the remainder over the original denominator as the fractional part.

Let's solve:

Step 1: Perform the division $7 \div 2$ .

Step 2: The quotient is 3, and the remainder is 1. This can be calculated as follows:
$7 \div 2 = 3$ with a remainder of 1 (since $2 \times 3 = 6$ and $7 - 6 = 1$ ).

Step 3: The mixed number representation of this division is:
$3\frac{1}{2}$ .

Therefore, the improper fraction $\frac{7}{2}$ is equal to the mixed number $3\frac{1}{2}$ .

Final Answer

$3\frac{1}{2}$

Key Points to Remember

Essential concepts to master this topic

Division Rule: Divide numerator by denominator for quotient and remainder
Technique: $7 \div 2 = 3$ remainder 1 gives whole number 3
Check: $3\frac{1}{2} = \frac{7}{2}$ because $3 \times 2 + 1 = 7$ ✓

Common Mistakes

Avoid these frequent errors

Using remainder as denominator instead of original denominator
Don't write $3\frac{2}{1}$ when remainder is 1! This creates nonsensical results because you're changing the fraction's value. Always keep the original denominator 2 and use remainder 1 as the new numerator: $3\frac{1}{2}$ .

How do I check if my mixed number is correct?

Convert it back to an improper fraction! Multiply the whole number by the denominator, then add the numerator: $3 \times 2 + 1 = 7$ , so $3\frac{1}{2} = \frac{7}{2}$ ✓

Why can't I just guess the answer?
