Estimate 75,572-22,468 by first rounding each number to the nearest thousand

54000

Step-by-step explanation:

First, round.

75572=76000

22468=22000

Then solve.

76000-22000=54000

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.
