Hej!
5/6 • 3/5 = 15/30 = 1/2
2/9 • 6/7 = 12/63 = 4/21
1 4/9 • 12 = 13/9 • 12 = 13/3 • 4 = 52/3 = 17 i 1/3
4 2/7 • 3 1/2 = 30/7 • 7/2 = 30/2 = 15
(3/4)² = 3²/4² = 9/16
(3/7)² = 3²/7² = 9/49
(2/3)³ = 2³/3³ = 8/27
(2/5)² = 2²/5² = 4/25
(1 1/4)² = (5/4)² = 5²/4² = 25/16 = 1 9/16
(1 1/4)³ = (5/4)³ = 5³/4³ = 125/64 = 1 61/64
(1 2/3)³ = (5/3)³ = 5³/3³ = 125/27 = 4 17/27
(2 1/2)² = (5/2)² = 5²/2² = 25/4 = 6 1/4
