Video Solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Convert each mixed number to an improper fraction.
  • Step 2: Perform the division by multiplying by the reciprocal of the divisor.
  • Step 3: Simplify the resulting fraction if necessary.

Now, let's work through each step:
Step 1: Convert the mixed number 4144\frac{1}{4} to an improper fraction. This is done by multiplying the whole number by the denominator and adding the numerator: 4×4+1=174 \times 4 + 1 = 17. So, 414=1744\frac{1}{4} = \frac{17}{4}.
Convert 2182\frac{1}{8} to an improper fraction: 2×8+1=172 \times 8 + 1 = 17. Therefore, 218=1782\frac{1}{8} = \frac{17}{8}.

Step 2: Divide the fractions by multiplying by the reciprocal of the divisor. In this case, divide 174\frac{17}{4} by 178\frac{17}{8}, which is equivalent to multiplying 174\frac{17}{4} by 817\frac{8}{17}:
174×817=17×84×17=13668\frac{17}{4} \times \frac{8}{17} = \frac{17 \times 8}{4 \times 17} = \frac{136}{68}.

Step 3: Simplify the resulting fraction 13668\frac{136}{68}. Since the numerator and the denominator are both divisible by 68, simplification gives: 136÷6868÷68=21=2\frac{136 \div 68}{68 \div 68} = \frac{2}{1} = 2.

Therefore, the solution to the problem is 2 2 .
