Video Solution

Step-by-Step Solution

To solve the problem 517×1345 \frac{1}{7} \times 1 \frac{3}{4}, we will first convert both mixed numbers into improper fractions and then multiply them.

  • Convert each mixed number to an improper fraction:
    For 5175 \frac{1}{7}: Multiply the whole number 5 by the denominator 7 and add the numerator 1: 5×7+1=365 \times 7 + 1 = 36. Therefore, 5175 \frac{1}{7} becomes 367\frac{36}{7}.
    For 1341 \frac{3}{4}: Multiply the whole number 1 by the denominator 4 and add the numerator 3: 1×4+3=71 \times 4 + 3 = 7. Therefore, 1341 \frac{3}{4} becomes 74\frac{7}{4}.
  • Multiply the improper fractions:
    Multiply the numerators: 36×7=25236 \times 7 = 252.
    Multiply the denominators: 7×4=287 \times 4 = 28.
    Thus, 367×74=25228\frac{36}{7} \times \frac{7}{4} = \frac{252}{28}.
  • Simplify the resulting fraction, 25228\frac{252}{28}:
    Divide both the numerator and denominator by their greatest common divisor, which is 28:
    252÷28=9252 \div 28 = 9 and 28÷28=128 \div 28 = 1.
    So, 25228=9\frac{252}{28} = 9.

Therefore, the solution to the problem is 99.
