Question

Afla a+b daca a=1/5+3/5+1\5+8\5-1 b=2\5+10\5-1+5\5-4\5.

Answer 1

Explicație pas cu pas:

Afla a+b daca a=1/5+3/5+1\5+8\5-⁵1=

(1+3+1+8-5)/5=8/5

b=2\5+10\5-⁵1+5\5-4\5=(2+10-5+5-4)/5=

8/5

a+b=8/5+8/5=16/5

Answer 2

Răspuns:

Explicație pas cu pas:

a = 1/5 + 3/5 + 1/5 + 8/5 - 1 = 13/5 - 1 = 13/5 - 5/5 = 8/5

b = 2/5 + 10/5 - 1 + 5/5 - 4/5 = 13/5 - 1 = 13/5 - 5/5 = 8/5

a + b = 8/5 + 8/5 = 16/5
