3/4+2c5/8= 6/8 + 2c 5/8 = 2c 11/8 = 3c 3/8
3/4+1c1/2= 3/4 + 1c 2/4 = 1c 5/4 = 2c 1/4
2c5/8+1c1/2= 2c 5/8 + 1c 4/8 = 1c 9/8 = 2c 1/8
3/4-2c5/8= ?
2c5/8-3/4= 2c 5/8 - 6/8 = 1c 13/8 - 6/8 = 1c 7/8
3/4-1c1/4= ?
1c1/2-3/4= 1c 2/4 - 3/4 = 6/4 - 3/4 = 3/4
1)³/₄ + 2⁵/₈ = 2¹⁴/₁₆
2)³/₄ + 1¹/₂ = 2³/₄
3)2⁵/₈ + 1¹/₂ = 4³/₈
4)³/₄ - 2⁵/₈ = -2⁶/₈
5)2⁵/₈ - ³/₄ = 2¹/₈
6)³/₄ - 1¹/₄ = -1²/₄
7)1¹/₂ - ³/₄ = ³/₄
8)³/₄ * 2⅝ = 1³¹/₃₂
9)³/₄ * 1½ = 1⅛
10)2⅝ * 1½ = 1³¹/₃₂
11)¾ / 2⅝ = ²/₇
12)¾ / 1¼ = ⅗
13)1½ / ¾ = 2
Mam nadzieję, że pomogłam:) Pozdrawiam.
