Simplify 0.5 of 1.5 of 2 as a single fraction

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.

12cm

the answer is d

6mm^3 or .6cm^3

factor trees are nice.

i would say true? if the unit was informational and it "refreshed your understanding", then true.
