2. last year, kimberly's history and math classes had regular tests. each history test had 9 questions and each math test had 20 questions. if kimberly had to answer the same number of history questions and math questions last year, what is the smallest number of each type of question she must have answered?

Replace  with

20

and simplify.

9,20

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.

12.5 feet
