Bridget knit a total of 15 centimeters of scarf over 3 nights. How many nights will Bridget have to spend knitting in order to knit a total of 40 centimeters of scarf? Solve using unit rates. Please explain

It will take Bridget 8 nights to knit 40 centimeters. You can get this answer because if Bridget knits 15 centimeters in 3 nights then she knits 5 centimeters every night. From then on all you have to do is divide 40/5 to get the answer.

Have a lovely day and Brainliest would be nice;)

Ithink it's the first one ( let me know if it right)

31/6= 19/6 19/6 *1/7=19/42
