If 8 pigs can fit in a pen, how many pens are necessary to make sure 71 pigs are all in a pen?

9

Step-by-step explanation:

Each pen can only hold 8 pigs, and pens cannot be split up into fractions.

Divide. 71 / 8 = 8.875

There is no 7/8 of a pen, so you must round up.

8.875 → 9.

$32,660

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
