Full solution

Q. Evaluate.\newline47÷72= \frac{4}{7} \div \frac{7}{2}=
  1. Understand the operation: Understand the operation to be performed.\newlineWe need to divide the fraction (4)/(7)(4)/(7) by the fraction (7)/(2)(7)/(2). In mathematical terms, this is written as (47)÷(72)(\frac{4}{7}) \div (\frac{7}{2}).
  2. Convert to multiplication: Convert the division of fractions into multiplication.\newlineTo divide by a fraction, we multiply by its reciprocal. The reciprocal of (72)(\frac{7}{2}) is (27)(\frac{2}{7}).\newline(47)÷(72)=(47)×(27)(\frac{4}{7}) \div (\frac{7}{2}) = (\frac{4}{7}) \times (\frac{2}{7})
  3. Multiply numerators and denominators: Multiply the numerators and denominators.\newlineNow we multiply the numerators together and the denominators together.\newline(4×2)/(7×7)=8/49(4 \times 2) / (7 \times 7) = 8 / 49
  4. Simplify the fraction: Simplify the fraction if possible.\newlineIn this case, the fraction 849\frac{8}{49} is already in its simplest form, as 88 and 4949 have no common factors other than 11.
