2 3 Divided By 2 In Fraction Form Trips Up Many Learners
2 3 divided by 2 in fraction form explained step by step
The expression 2 3 divided by 2 means taking the mixed number 2 3/2 and dividing it by 2. First, convert the mixed number to an improper fraction, then perform the division. The result is a precise fraction that you can simplify if possible.
Step 1: Convert the mixed number to an improper fraction. A mixed number a b/c equals (axc + b)/c. For 2 3/2, this gives (2x2 + 3)/2 = (4 + 3)/2 = 7/2. Now we have the improper fraction 7/2.
Step 2: Divide the improper fraction by 2. Dividing by 2 is the same as multiplying by 1/2. Therefore, (7/2) ÷ 2 = (7/2) x (1/2) = 7/4. The fraction 7/4 is already in simplest terms, since 7 and 4 share no common factors other than 1.
Step 3: (Optional) Convert back to a mixed number. If you prefer a mixed number, 7/4 = 1 3/4. This shows the same value in a different form.
Summary: The exact fraction form of 2 3 divided by 2 is 7/4, which is equivalent to the mixed number 1 3/4.
Frequently asked questions
How do I handle other mixed numbers divided by a whole number? Convert the mixed number to an improper fraction, then multiply by the reciprocal of the divisor. For example, (3 5/6) ÷ 4 = (23/6) ÷ 4 = (23/6) x (1/4) = 23/24.
Can this be represented as a decimal? Yes. 7/4 equals 1.75 in decimal form. When converting fractions to decimals, divide the numerator by the denominator.
Why is converting to an improper fraction helpful? It makes division straightforward because you can apply multiplication by the reciprocal, which is easier to compute and less error-prone.
