Question

Which equation correctly represents the distance between −15.1 and −3.9 on a number line?

|−3.9−(−15.1)|=11.2
−3.9−15.1=−11.2
|−15.2+(−3.9)|=19
−15.1−3.9=−19

Answer 1

Here what we observe

• -3.9>-15.1

So as we know about subtracting lowest number is subtracted from highest no

So here

$\\ \tt\longmapsto -3.9-(-15.1)=|-11.2|=11.2$

Distance must be positive
