One year ago, he had height of 150 cm.
Step-by-step explanation:
We have to model this situation.

Each m is 100 cm. So 10cm = 10/100 = 0.1m.

His height is now 1.6m, which is 10cm = 0.1m above his height last year, which was x. So
His height last year was 1.5m.
In centimeters, that is 1.5*100 = 150 cm.
