Question

Krysta knit a total of 16 centimeters of scarf over 8 nights. How many nights will Krysta have

to spend knitting in order to knit a total of 46 centimeters of scarf? Assume the relationship is
directly proportional.
nights

Answer 1

23 nights

Explanation:

What does "Proportional" Mean? Proportional means that the ratio is the same throughout.

Step One: First, to set this up, we will put the 16 centimeters for the numerator and then the 8 nights on the bottom. The bottom is the independent variable because we can't physically change the number of nights. 16/8.

Step Two: Now, we have to scale this up to 46. Because the 46 is the centimeters, we have to do 46/16 to see how much we need to scale it by: 46/16= 2.875.

Step Three: Lastly, we can multiply 8 by 2.875 to see how many nights it took: 8 times 2.875 is 23 nights.
