Answer 2

Odpowiedź:

Uzupełnij graf.

0,2 + 2/5 = 2/10 + 4/10 = 6/10 = 3/5 = 0,6

3/5 : 3/4 = 3/5 * 4/3 = 4/5 = 0,8

0,8 - 0,5 = 8/10 - 5/10 = 3/10 = 0,3

0,3 + 1,2 = 1,5

1,5 * 2 2/5 = 1,5 * 2,4 = 3,6

3,6 : 0,09 = 360 : 9 = 40

40 - 38,8 = 1,2

1,2 : 3,6 = 12/10 *10/36 = 1/3

1/3 + 2 1/6 = 2/6 + 2 1/6 = 2 3/6 = 2 1/2

2 1/2 * 2/25 = 5/2 * 2/25 = 1/5 = 2/10 = 0,2
