1 /17 * 2 1/8=

2 1/2 : 1 1/4=

5 2/3 : 2 /16=

4 3/5 + 2 3/4=

12 2/7 -6 1/2=

Answer 1

3/4 liczby 50 =¾ · ⁵⁰/₁ = ¹⁵⁰/⁴ = 37,5

7/10 liczby 12 1/2= ⁷/₁₀ · ²⁵/₂ = ¹⁷⁵/₂₀ = 8 ¾

3 3/7 liczby 2 5/6= ²⁴/⁷ · ¹⁷/₆ = ⁴⁰⁸/₄₂ = 9³⁰/₄₂ = 9¹⁵/₂₁ = 9 ⁵/₇

7 1/2 * 2 1/15= ¹⁵/₂ · ³¹/₁₅ = ³¹/₂ = 15¹/₂

1 /17 * 2 1/8= ¹/₁₇ · ¹⁷/₈ = ⅛

2 1/2 : 1 1/4= ⁵/₂ ·⅘ = 2

5 2/3 : 2 /16= ¹⁷/₃ · ¹⁶/₃₃ = ²⁷²/₉₉ = 2 ⁷⁴/₉₉

4 3/5 + 2 3/4= ²³/₅ + ¹¹/₄ = ⁹²/₂₀ + ⁵⁵/₂₀ = ¹⁴⁷/₂₀ = 7 ⁷/₂₀

12 2/7 -6 1/2= ⁹⁶/₇ - ¹³/₂ = ¹⁹²/₁₄ - ⁹¹/₁₄ = ¹⁰¹/₁₄  = 7 ³/₁₄

7 2/3 - 5 5/6= ²³/₃ - ³⁵/₆ =  ⁴⁶/₆ - ³⁵/₆ = ¹¹/₆ = 1⅚

Answer 2

3/4 liczby 50 = 50×¾37,5

 

7/10 liczby 12 1/2= 12½×7/10= 8,75

 

3 3/7 liczby 2 5/6= 2⅚ × 3³/₇ =9 5/7

7 1/2 * 2 1/15= 15,5

1 /17 * 2 1/8= 1/8

2 1/2 : 1 1/4= 2

5 2/3 : 2 /16= 45 1/135

4 3/5 + 2 3/4= 7,35

12 2/7 -6 1/2=5 11/14

7 2/3 - 5 5/6=1⅚
