Answer 1

Respuesta:

131/9

Explicación paso a paso:

15-(25/7 - 7/2)+(4/18 * 8/5)

15-(25/6 - (7*3)/(2*3))+(4*8/(18*5))

15-(25/6 - (21/6))+(32/90)

15-((25-21)/6)+16/45

15-(4/6)+16/45

15-4/6+16/45

15-(4*9)/(6*9)+16/45

15-36/45+16/45

15+(16-36)/45

15+(-20/45)

15-20/45

15-4/9

(15*9-4)/9=131/9
