Pedro, Lena, Harriet, and Yermin each plot a point to approximate StartRoot 0.50 EndRoot. Pedro A number line going from 0 to 0.9 in increments of 0.1. A point is between 0.2 and 0.3.

Lena A number line going from 0 to 0.9 in increments of 0.1. A point is between 0.4 and 0.5.

Harriet A number line going from 0 to 0.9 in increments of 0.1. A point is at 0.5.

Yermin A number line going from 0 to 0.9 in increments of 0.1. A point is just to the right of 0.7.

Whose point is the best approximation of StartRoot 0.50 EndRoot?
Pedro
Lena
Harriet
Yermin
HEL!,!!
