Please show each mathematical step with formula and explain. thank you

In a very simplistic example, a bank has only two positions on its balance sheet: - On the asset side, there is a loan with an outstanding amount of EUR 50.000 , a (remaining) maturity of 9 months (or 270 days) and an interest rate of 1.5% (fixed). - On the liabilities side, there is a EUR 50.000 cash deposit with a maturity of 1 month (or 30 days) at an interest rate of 0.125% (fixed). b) How can the bank hedge its exposure when using the "matched book" approach? (i.e. what types of products should be bought, sold or replaced?)
