Question

G h i prosze o zrobienie

Answer 1

G)
(6,5- 4,7) : (4 - 2 1/5)= 1,8 : 1 4/5= 1,8 : 1,8= 1
H)
(1,5 - 1 1/3) * 2 2/5 - 0,1 = (1 15/30 - 1 10/30) * 2 2/5 - 1/10 = 5/30* 12/5 - 1/10 = 4/10 - 1/10 = 3/10

Answer 2

(6,5 - 4,7) : (4-2 1/5) = 1,8 : (3 5/5 - 2 1/5) = 1,8 : 1 4/5 = 18/10 * 5/9 = 2/2 * 1 = 1
(1,5 - 1 1/3) * 2 2/5 - 0,1 = (15/10 - 4/3) * 12/5 - 0,1 = (45/30 - 40/30) * 12/5 - 1/10 = 5/30 * 12/5 - 1/10 = 2/5 - 1/10 = 4/10 - 1/10 = 3 / 10 = 0,3
