Question

Determine el valor numérico de:
C=3/5÷8/15-3/5⋅(2/5-12/7)+ (5 2/7-3/7)

Answer 1

Problema

C = 3/5÷8/15 - 3/5•(2/5-12/7) + (52/7-3/7)

Resolviendo

C = (15•3)/(5•8) - 3/5•(14/35-60/35) + 49/7

C = 9/8 - 3/5•(-46/35) + 7

C = 9/8 - (-46•3)/(35•5) + 7

C = 9/8 - (-138/175) + 7

C = 9/8 + 138/175 + 7

C = 1575/1400 + 1104/1400 + 9800/1400

C = 12479/1400

FORMA DECIMAL

C = 8,914
