Jerome's rain gauge showed 13 9/10 centimeters at the end of last month. At the end of this month, the rain gauge showed 15 3/10 centimeters. How many more centimeters of rain fell this month

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

I got 2 and 1/10

I turned it in an improper fraction
