Step-by-Step Solution

To solve the given problem, we need to divide the mixed number by the fraction 23\frac{2}{3}. Here's a detailed step-by-step solution:

Step 1: Convert Mixed Number to Improper Fraction.
The mixed number 1121\frac{1}{2} can be converted into an improper fraction. Multiply the whole number 1 by the denominator 2, and add the numerator 1. This gives us:

1×2+1=2+1=3 1 \times 2 + 1 = 2 + 1 = 3 Thus, the improper fraction is 32\frac{3}{2}.

Step 2: Divide by the Fraction 23\frac{2}{3}.
Dividing by a fraction is equivalent to multiplying by its reciprocal. So, 32÷23\frac{3}{2} \div \frac{2}{3} becomes 32×32\frac{3}{2} \times \frac{3}{2}.

Step 3: Perform the Multiplication.
Multiply the numerators together and the denominators together:

32×32=3×32×2=94 \frac{3}{2} \times \frac{3}{2} = \frac{3 \times 3}{2 \times 2} = \frac{9}{4}

Step 4: Convert to a Mixed Number if Needed.
Convert 94\frac{9}{4} back to a mixed number. Divide 9 by 4, which gives 2 with a remainder of 1:

9÷4=2(whole number),remainder 1 9 \div 4 = 2 \quad \text{(whole number)}, \quad \text{remainder } 1 Thus, 94=214\frac{9}{4} = 2\frac{1}{4}.

Therefore, the solution to the problem is 214\boxed{2\frac{1}{4}}.

Answer

214 2\frac{1}{4}
