Hello!

Answer:

  • 1.) 14/15

Solution:

  • 3/5 + 2/6
  • = 3×6/5×6 + 2×5/6×5
  • = 18/30 + 10/30
  • = 28/30
  • = 28÷2/30÷2
  • = 14/15

Answer:

  • 2.) 1/3

Solution:

  • 4/6 - 1/3
  • = 4/6 - 1×2/3×2
  • = 4/6 - 2/6
  • = 4-2/6
  • = 2/6
  • = 2÷2/6÷2
  • = 1/3

Answer:

  • 3.) 9/14

Solution:

  • 1/7 + 1/2
  • = 1×2/7×2 + 1×7/2×7
  • = 2/14 + 7/14
  • = 2+7/14
  • = 9/14

Answer:

  • 4.) 1/5

Solution:

  • 6/10 - 2/5
  • = 6/10 - 2×2/5×2
  • = 6/10 - 4/10
  • = 6-4/10
  • = 2/10
  • = 2÷2/10÷2
  • = 1/5

Answer:

  • 5.) 1 13/24

Solution:

  • 7/8 + 2/3
  • = 7×3/8×3 + 2×8/3×8
  • = 21/24 + 16/24
  • = 21+16/24
  • = 37/24 = 1 13/24
