Full solution

Q. (68)×(78)\left(\frac{6}{8}\right)\times\left(\frac{7}{8}\right)
  1. Simplify Fractions: Simplify the fractions before multiplying if possible.\newlineBoth 66 and 88 can be divided by 22 to simplify the first fraction.\newline6÷2=36 \div 2 = 3\newline8÷2=48 \div 2 = 4\newlineSo, (68)(\frac{6}{8}) simplifies to (34)(\frac{3}{4}).
  2. Check Second Fraction: Check if the second fraction (78)(\frac{7}{8}) can be simplified.\newlineSince 77 is a prime number and 88 cannot be divided by 77 to give a whole number, the fraction (78)(\frac{7}{8}) cannot be simplified further.
  3. Multiply Fractions: Multiply the simplified first fraction by the second fraction.\newline(34)×(78)=(3×74×8)(\frac{3}{4}) \times (\frac{7}{8}) = (\frac{3 \times 7}{4 \times 8})\newlineCalculate the numerator and the denominator separately.
  4. Calculate Numerator: Calculate the numerator.\newline3×7=213 \times 7 = 21
  5. Calculate Denominator: Calculate the denominator. 4×8=324 \times 8 = 32
  6. Write Product: Write the product of the two fractions.\newline(34)×(78)=2132(\frac{3}{4}) \times (\frac{7}{8}) = \frac{21}{32}\newlineThis fraction cannot be simplified further as 2121 and 3232 have no common factors other than 11.
