The height of Jerome's rain gauge increased #14/10=1 2/5# cm.

Explanation:

To calculate the difference we have to substract 2 mixed numbers (having integer part and a fraction). To do so we can first transform both numbers to improper fractions and then substract the numerators.

#15 3/10-13 9/10=153/10-139/10=(153-139)/10=14/10=1 4/10=1 2/5#
