Wendy's hair was 45 cm long. She got 19% cut off. How long is her hair now?

36.45 cm

Step-by-step explanation:

You can automatically assume that if it was 20% cut off, Wendy's hair would've been 36 cm.  Multiply 45 by 0.19 to get 8.55 since that is how much Wendy's hair is being cut off.  Subtract that number from 45 to get your final answer which is 36.45 cm.

option 1

data plot with   3 dots over 33, 1 dot over 34, 2 dots over 35, no dot over 36, 1 dot over 37, 2 dots over 38, 4 dots over 39, and 2 dot over 40.

a = 11 : 4

b = 38

c = 1 for every 6
