Lexi knit a total of 12 centimeters of scarf over 3 nights. After 4 nights of knitting, how many centimeters of scarf will Lexi have knit in total? Solve using unit rates.

16 centimeters.

Step-by-step explanation:

if we were two equally divide 12 centimeters by three nights, we would get 4 centimeters a night. using this method, we can determine that after four nights of knitting, at four centimeters a night, she would have knitted 16 centimeters of a scarf.

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.
