Answer 1

Explicație pas cu pas:

2.a=3×(1/2 -1/3+1/6) => a=3×(3/6-2/6+1/6) => a=3×2/6 => a=1

b=5/3 :(1/2+1/4-1/3)=>b=5/3:(6/2+3/12-4/12)=>b=5/3:5/12=>b=5/3×12/5=>b=4

mg=Va×b=V1×4=V4=2

3.73:n=c1 r=1 => 73=nc1+1 => nc1=72

123:n=c2 r=3 =>123=nc2+3=>nc2=120

223:n=c3 r=7 => 223=nc3+7=>nc3=216

deci n|72 ,n|120, n|216

si cum n cel mai mare => n=(72,120,216)

=>n=24
