Question

va rog frumos cat se poate de repede​

Answer 1

Răspuns:

4/5 * [2/2*(1/2-1/4)]

Amplificam 1/2 cu 2:

2/4-1/4=1/4 deci avem:

4/5*2/2*1/2=

8/10*1/2=8/20

B)4/3-2/3*(5/6+1/3)]*3/10=

4/3-2/3*(5/6+ 1/3 pe care il amplificam cu 2=

4/3-2/3*(5/6+2/6)*3/10

(4/3-2/3*7/6)*3/10

(4/3-14/18) *3/10

(4/3 pe care il amplificam cu 6=

(24/18-14/18) * 3/10

10/18*3/10=30/180 daca il simplificam cu 30=

1/6

Sper ca te am ajutat!
