- 1/2 x 2 is equal to *
А. 1
В. 1/4
с. -1/4
D. -1

i believe it would be d. -1

explanation:

you just cancel the common factor which is 2

then rewrite the expression

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.
