Answer 1

a)0,6+2/3=3/5+2/3=19/15

b)0,25+7/30=1/4+7/30=29/60

c)7,05-1/60=141/20-1/60=211/30

d)0,12×5/6=3/25×5/6=1/5×1/2=1/10

e)0,001:(2+1/25)=1/1000:51/25=1/1000×25/51=1/40×1/51=1/2040

Answer 2

Răspuns:

Explicație pas cu pas:

a)

6/10 + 2/3 = 3/5 + 2/3 = 9/15 + 10/15 = 19/15

b)

0,25 + 7/30 = 25/100 + 7/30 = 1/4 + 7/30 = 15/60 + 14/60 = 29/60

c)

7.05 - 1/60 = 705/100 - 1/60 = 141/20 - 1/60 = 423/60 - 1/60 = 422/60 = 211/30

d)

12/100 * 5/6 = 2/20 = 1/10

e)

1/1000 : (50/25 + 1/25) = 1/1000 : 51/25 = 1/1000 *25/51 = 1/51*40 = 1/2040
