Tuone kama tunaweza kuandika 0.15 kama sehemu.

Kitu cha muhimu hapa ni kuangalia

nafasi ipi tarakimu izi zipo.

Kwa hiyo hii 1 hapa, iko kwenye sehemu ya makumi,

unaweza kuiona kama 1 mara 1/10.

Hii 5 hapa ipo kwenye sehemu ya mamia,

unaweza kuiona kama 5 mara 1/100.

Kama nitaiandika hii , nitaandika kama

jumla ya -- hii 1 inawakilisha 1 mara 1/10,

kwa hiyo kimsingi itakuwa 1/10 jumlisha

na hii 5 inawakilisha5 mara 100,

hivyo itakuwa jumlisha 5/100.

Na kama tunataka kuzijumlisha,

tunataka kupata viasili vyenye kufanana.

Asili zenye kufanana ni 100.

10 zote na --kigawe kidogo cha ushirika.

100 ni kigawe cha 10 na 100.

Hivyo tunaweza kuandika hii kama kitu juu ya 100

jumlisha kitu juu ya 100.

Hii haibadilika.

Hii ilishakuwa 5/100.

Kama tukizidisha asili hapa

kwa 10-- hiki ndo tunachokifanya; tunazidisha kwa 10--

baadae tutatakiwa tuzidishe hii asili kwa 10.

Na hii ni sawa na 10/100.

Na hapa tushajumlisha.

Hii ni sawa na 10 jumlisha 5 ni 15/100.

Na unatakiwa kufanya hii haraka kidogo

kwa kutambua hii.

Unaweza sema, angalia, nafasi yangu ndogo hapa

ni kwenye sehemu ya mamia.

Badala ya kuiita hii 1/10, nitaiita hii

10/100.

Au ninaweza kusema hii yote ni 15/100.

Na kama nataka kupunguza hii kwenye kiwango cha chini,

tutapata ngoja tuone, zote kiasi na asili

zinagawanyika kwa 5.

Hivyo ngoja tugawanye zote kwa 5.

Kwa hiyo kiasi , 15 gawanya kwa 5, ni 3.

Asili, 100 gawanya kwa 5, ni 20.

Na hii inahusu kurahisisha kadri tutakavyopata.
