Step 1: Tambua nafasi ya mamia ya desimali (hundredths place). Katika namba 399.90485, namba iliyo katika nafasi ya mamia ya desimali ni 0 (namba ya pili baada ya desimali). Step 2: Angalia namba inayofuata kulia kwa nafasi ya mamia ya desimali. Namba inayofuata kulia kwa 0 ni 4. Step 3: Tumia sheria za kuzungusha. Ikiwa namba inayofuata ni 5 au zaidi, zungusha namba ya mamia ya desimali juu. Ikiwa ni chini ya 5, acha namba ya mamia ya desimali kama ilivyo. Kwa kuwa 4 ni chini ya 5, namba 0 inabaki vile vile. Step 4: Zungusha namba. 399.90485 imezungushwa hadi mamia ya desimali inakuwa 399.90. 399.90 3 done, 2 left today. You're making progress.
