Grandpa Ernie is shrinking! Over the past 4years, his height decreased by a total of 2.4 cm. It decreased by the same amount each year.

What was the change in Grandpa Ernie's height each year?

0.6

Step-by-step explanation:

If grandpa Erine Shrinks by 2.4cm in 4 years then we would have to divide 2.4cm by 4 in order to get the amount of the change in one year.

4x = 2.4cm

divide 4 by both sides of the equation

x = 0.6cm

therefor, 0.6cm is the change in grandpa ernies hight each year.
