Solve Mixed Number Division: 3⅝ ÷ 1½ Step-by-Step

Question

358:112= 3\frac{5}{8}:1\frac{1}{2}=

Video Solution

Step-by-Step Solution

To solve this problem, we need to proceed through the following steps:

  • Step 1: Convert the mixed numbers to improper fractions.
  • Step 2: Divide the improper fractions using multiplication by the reciprocal.
  • Step 3: Simplify the resulting fraction and convert back to a mixed number.

Now, let's work through each step:

Step 1: Convert
For 358 3\frac{5}{8} , multiply the whole number 3 by the denominator 8 and add the numerator 5:
3×8+5=24+5=29 3 \times 8 + 5 = 24 + 5 = 29
<=><=> This gives us the improper fraction 298\frac{29}{8}.

For 112 1\frac{1}{2} , multiply the whole number 1 by the denominator 2 and add the numerator 1:
1×2+1=2+1=3 1 \times 2 + 1 = 2 + 1 = 3
<=><=> This gives us the improper fraction 32\frac{3}{2}.

Step 2: Divide the improper fractions.
298÷32\frac{29}{8} \div \frac{3}{2} becomes 298×23\frac{29}{8} \times \frac{2}{3}.
Multiply the numerators and the denominators:
29×28×3=5824\frac{29 \times 2}{8 \times 3} = \frac{58}{24}.

Step 3: Simplify the resulting fraction.
Divide both the numerator and the denominator by their greatest common divisor, which is 2:
58÷224÷2=2912\frac{58 \div 2}{24 \div 2} = \frac{29}{12}.
Convert 2912\frac{29}{12} into a mixed number:
29÷12=2 remainder 5 29 \div 12 = 2 \text{ remainder } 5
Thus, it becomes 2512 2\frac{5}{12}.

Therefore, the division of 358 3\frac{5}{8} by 112 1\frac{1}{2} yields 2512 2\frac{5}{12} .

Answer

2512 2\frac{5}{12}
