Question

1. Oblicz

a)4,8•3¹/₈ : 2⁴/₇

b)3⁵/₉ : 0.96 • 0.54

c)⅔ liczby 16.2

d)⅘ liczby 2.25

e)0.21 liczby 6³/₇

Answer 1

a)4,8•3¹/₈ : 2⁴/₇ =  4 8/10∧ 25/8 : 18/7 = 24/5 ∧ 25/8 ∧ 7/18 = 3 ∧ 5 ∧ 7/18 = 35/6 = 5 5/6

 

 

b)3⁵/₉ : 0.96 • 0.54 = 32/9 : 96/100 ∧ 54/100 = 32/9 ∧ 100/96 ∧ 54/100 = 2

 

 

c)⅔ liczby 16.2 = ⅔ ∧ 16,2 = ⅔ ∧ 16 2/10 = 2/3 ∧ 162/10 = 54/5 = 10 4/5

 

d)⅘ liczby 2.25 = 4/5 * 2,25 = 4/5 * 225/100 = 18

 

e)0.21 liczby 6³/₇ = 0,21 * 6 3/7 = 21/100 * 45/7 = 3/20

Answer 2

a)4i8/10x25/8:18/7=48/10x10/25x7/18=48/25x7/18=56/75

b) 32/9:96/100x54/100=32/9x100/96x54/100=32/9x54/96=2

c)16,2x2/3=162/10x2/3=108/10=10i8/10=10,8

d)2,25x4/5=225/100x4/5=225/125=9/5=1i4/5=1,2

e)6i3/7x0,21=35/7x21/100=105/100=1i5/100=1,05
