Să mă ajute cineva dau coroana !​

Answer 1

Răspuns:

a) 1/2+1/2=2/2=1

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

3/4+1/4=4/4=1

4/5+1/5=5/5=1

1+1+1+1=4

b) 1/11=4/44(amplificare cu 4)

1/22=2/44(amplificare cu 2)

2/11=8/44(amplificare cu 4)

3/22=6/44(amplificare cu 2)

4/44+2/44+3/44+2/44+8/44+6/44+5/44+7/44+9/44=44/44=1

Sper ca nu am gresit sa calcule.
