Question

Karen is using a number line to represent the doors in the school hallway.
She labels 0.25, 0.5, and 0.75 on the number line as a scale reference.
Where should Karen place a mark to represent a door that is 0.7 from the start of the hallway?
Explain.

Answer 1

In between .5 and .25, and if I am wrong, sorry for not understanding 2nd grade math number lines.

Answer 2

clearly, at the 0.7 distance.
That is, 4/5 of the way from 0.5 to 0.75
