Full solution

Q. On Sunday, 1/61/6 of the dogs seen in the park were on leashes. On Wednesday, 3/73/7 of the dogs in the same park were on leashes. Which day had a greater fraction of dogs on leashes?\newlineA)Sunday\newlineB)Wednesday\newline
  1. Understand fractions given: Understand the fractions given for each day.\newlineOn Sunday, the fraction of dogs on leashes is (1)/(6)(1)/(6).\newlineOn Wednesday, the fraction of dogs on leashes is (3)/(7)(3)/(7).\newlineWe need to compare these two fractions to determine which is greater.
  2. Compare fractions directly: Compare the two fractions directly.\newlineSince the denominators are different 66 and 77, we cannot directly compare the fractions by looking at the numerators. We need to find a common denominator or use another method to compare the fractions.
  3. Use cross-multiplication: Use cross-multiplication to compare the fractions.\newlineCross-multiply the fractions to compare their sizes without finding a common denominator. Multiply the numerator of the first fraction by the denominator of the second fraction and vice versa.\newline(1)/(6)(1)/(6) compared to (3)/(7)(3)/(7) becomes:\newline1×7=71 \times 7 = 7 (for Sunday)\newline3×6=183 \times 6 = 18 (for Wednesday)
  4. Determine greater product: Determine which product is greater.\newlineThe product for Sunday is 77, and the product for Wednesday is 1818. Since 1818 is greater than 77, the fraction (3)/(7)(3)/(7) is greater than (1)/(6)(1)/(6).
  5. Conclude greater fraction day: Conclude which day had a greater fraction of dogs on leashes. Since (3)/(7)(3)/(7) is greater than (1)/(6)(1)/(6), Wednesday had a greater fraction of dogs on leashes than Sunday.
