Ok, good job for posting the answer
If you divide a fraction by another fraction, this is equivalent to mupltiplying by its inverse:
so
divided by
is equivalent to
multiplied by by
which is
so the answer is
which is also 0.5
Answer: large pizza
Work:
1) You can determine the arc of a slice that is 1/12 of the whole pizza using the diameter.
2) First, calculate the total circumference of each pizza.
Formula for the circumference: 2π×radius
radius = diameter / 2
medium pizza: 2π (12 / 2) = 12π ≈ 37.70 in
large pizza: 2π (16/2) = 16π ≈ 50.27 in
3) arc of a 1/12 sector
arc of a 1/12 sector = circumferece × 1/12
medium pizza: 37.70 in / 12 = 3.14 in
large pizza: 50.27 in / 12 = 4.19 ↔ this is pretty close to 4.25
So, at the end we have found that the sector of 4.25 in left belongs to a large pizza.
The first few multiples of 8 are: 8, 16, 24, 32, 40, and 48. The first multiples of 12 are: 12, 24, 36, 48, 60, and 72.
Common multiple of 8 and 12 are 24 and every subsequent multiple of 24.
As 8×3=24
12×2=24
So 24 is a common multiple of 8 and 12 this means the other common multiples of 8 and 12 are the multiples of 24 like 48, 72, 96 etc.
