Which fraction is bigger? W1-mt_IfEgu0X449-s1

  1. False · Both are one piece, but a fourth is a smaller piece than a half. A bigger denominator means smaller pieces.
  2. 4/5 · When the denominator is the same, the fraction with the bigger numerator is bigger. 4 fifths is more than 2 fifths.
  3. 4/5 · Same denominator (5), so compare the top numbers. 4 is more than 2, so 4/5 is bigger.
  4. False · It's the opposite. A bigger denominator means the whole is cut into more pieces, so each piece is smaller.
  5. Dan · Same denominator (7), so compare the top numbers. 6 is more than 3, so Dan ate more.
  6. 1/2, 1/3, 1/4 · Each fraction is one piece. The smallest denominator makes the biggest piece, so 1/2 is biggest and 1/4 is smallest.
  7. 2 · 1/4 and 1/5 are smaller than 1/3 because they have bigger denominators, so the answer is 2.
  8. 1/2, 1/3, 1/4, 1/6 · More pieces makes a smaller slice, so 1/2 is the biggest and 1/6 is the smallest.
  9. 1/8, 1/5, 1/3, 1/2 · The bigger the denominator, the smaller the piece, so 1/8 comes first and 1/2 comes last.
  10. No, 5/9 is bigger because 5 is more than 3 · The denominator is the same (9), so compare the top numbers. 5 is more than 3, so 5/9 is actually bigger.
