Step 1: Tambua urefu wa jumla wa gogo na urefu wa kila ubao. Urefu wa gogo ni 12.75 mita. Urefu wa kila ubao ni 2.5 mita. Step 2: Gawanya urefu wa jumla wa gogo kwa urefu wa ubao mmoja ili kupata idadi ya mbao zinazoweza kukatwa. Idadi ya mbao = Urefu wa gogoUrefu wa ubao mmoja; Idadi ya mbao = 12.75/2.5 Step 3: Fanya hesabu ya mgawanyiko. Ili kurahisisha mgawanyiko, tunaweza kuzidisha namba zote mbili (kinyume na kigawanyo) kwa 10 ili kuondoa desimali kwenye kigawanyo: (12.75 × 10)/(2.5 × 10) = 127.5/25 Sasa gawanya 127.5 kwa 25: 127.5/25 = 5.1 Step 4: Chagua idadi kamili ya mbao. Kutokana na matokeo ya 5.1, seremala anaweza kukata mbao kamili 5. Sehemu ya 0.1 inawakilisha kipande cha mbao ambacho hakitoshi kuwa ubao kamili. Idadi ya mbao kamili zinazoweza kukatwa ni 5. Jibu sahihi ni B.
