I don't need an answer, I just need someone to explain how to do it. <3

hi

Step-by-step explanation:

Proportions are two fractions (or rational numbers) that are equal to each other.

Fractions are considered equal if both the numerator and denominator can be multiplied or divided by the same constant to get the other 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.

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
