Question

calculează a b c apoi sumele a plus b plus c a plus b plus c unde a egal cu 5 supra 36 plus 1 supra 24 b egal cu 5 supra 12 plus 1 supra 24 egal cu 5 supra 48 plus 1 supra 36​

Answer 1

Răspuns:

Explicație pas cu pas:

a = ²⁾5/36 + ³⁾1/24 = 10/72 +3/72 = (10+3)/72 = 13/72

b = ²⁾5/12 + 1/24 = (10+1)/24 = 11/24

c = ³⁾5/48 + ⁴⁾1/36 = (15+4)/144 = 19/144

a+b = 13/72 + ³⁾11/24 = (13+33)/72 = 46/72⁽²=23/36

a+c = ²⁾13/72 + 19/144 = (26+19)/144 = 45/144⁽⁹ = 5/16

a+b+c = (a+c)+b = ³⁾5/16 + ²⁾11/24 = (15+22)/48 = 37/48
