Question

CALCULATI RESPECTAND ORDINEA EFECTUARII OPERATIILOR

Answer 1

[7la2/60:(-7/6)x4,3]•(-71:1,42)=[49/60•(-6)/7•43/10]•(-71:142/100)=[(-7)/10•43/10]•(-71•100/142)=(-301/100)•(-100/2)=301/2=150,5

Answer 2

49/60 * (-6/7) *43/10 * (-71 *100/142)=
= (-7/10) * 43/10 * (-100/2)=
= +301/100 * 100/2=
=301/2=
150,5
