Hi friends. Solve 6 11/12 − (24 1/6 + 3 2/3). Do the operation in parentheses first. Show all your steps.
Irina18 [472]

Answer:

Step-by-step explanation:

6 11/12-(24 1/6+3 2/3)

=(6×12+11)/12-[(24×6+1)/6+(3×3+2)/3]

=(72+11)/12-[(144+1)/6+(9+2)/3]

=83/12-[145/6+11/3]

=83/12-[(145+2×11)/6]

=83/12-[167/6]

=83/12-334/12

=(83-334)/12

=-251/12

=-20 11/12
