(C) Elijah’s prediction is high because 180 times one-fourth = 45.
Step-by-step explanation:
Because the spinner is divided into 4 equal sections, they all have an equal chance of being landed on. Therefore, you must do 180*1/4 which is 45. This means that's Elijah's prediction of 60 of the spins will result in 3 is too high.
Divide both numbers in one of the ratios by their highest common factor. This will give you the scale factor of the bigger triangle to the smaller triangle.
