Mr. Larson is planning the seating for school recital he needs to reserve 1/3 of the seats for students and 1/6 of the seats for parents after reserving seats for students and parents what fraction of the seats in the auditorium are left

1/2 of the auditorium is left

Step-by-step explanation:

1/3 - students

1/6 = 0.5/3 - parents

1/3 + 0.5/3 = 1.5/3

1.5/3 = 1/2

Therefore 1/2 of the auditorium is left

neither i nor ii 56 / 4.9 = 11.91489362 and 82 / (11+5) =5.125 so i is wrong

ii. (24/8+2) times 3 = 15 and (42+9)/2 =25.5

step-by-step explanation:

56

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
