The number h and 1.4 are additive inverses. drag and drop 1.4 and h to their correct positions on the number line. drag and drop the label “sum” to the sum of 1.4 and h.

We need to plot 1.4 and 1.4+h on the number line.

We know that h is the additive inverse of 1.4. The additive inverse of any number is the number which when added to the former number results in zero (0).

⇒ 1.4 + h = 0

⇒ h = -1.4

Hence, Sum = 0

Please refer to the attached image to see 'h', '1.4' and '1.4 + h' marked on the number line
