Write the missing decimal so that each pair adds to 1 1/2 + something = 1
2/5 + something= 1
9/10 + something= 1

Step-by-step explanation:

1/2 + 1/2 = 1

2/5 + 3/5= 1

9/10 + 1/10= 1

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.

its 8
