Answer 2

Jerome’s rain gauge shows that there’s 13 9/10 centimeter at the end of last month.
=> for the end of this month, it shows 15 3/10 centimeters.
The question is, how manu centimeter of rain added for this month according to Jerome’s gauge.
=> 15 3/10 cm (this month’s rain measurement)
=> 13 9/10 cm (last month’s rain measurement)
Subtract both numbers.
=> 15 3/10 – 13 9/10
=> convert this first to improper fraction
=> 153/10 – 139/10
=> 14/10
=> 1 4/10 the rain added to for this month
