Question

Pomóżcie z matematyki to dla koleżanki:
1/2 + 0,6 =
0,55 - 1/4 =
1,25 + 5/6 =
5/4 * 0,1 =
1,2 : 3/5 =
0,25 : 1/8 =

Answer 1

O,5 = 0,6=0,11
0,55-0,25=0,30
1i1/4=5/6=5/4=5/6=5/10=2
5/4*1/10=5/40
1i2/10:3/5=12/10:3/5=4/2

Answer 2

1/2 + 0,6 = 5/10 + 6/10 = 11/10 = 1 i 1/10

0,55 - 1/4 = 55/100 - 25/100 = 30/100 = 0,3

1,25 + 5/6 = 1 i 1/4 + 5/6 = 1 i 3/12 + 10/12 = 1 i 13/12 = 2 i 1/12

5/4 * 0,1 = 125/100 * 0,1 = 1,25 * 0,1 = 0,125

1,2 : 3/5 = 12/10 : 6/10 = 12/10 * 10/6 = 2

0,25 : 1/8 = 0,25 : 0,125 = 2

Answer 3

A)1,1
b)0.30
c)2 3/12 - dwa i 1 dwunasta
d)0.125
e) 2
f) 2
