Naombeni msaada katika hesabu hii!

[Msafiri Kasian]

Round off 324 589 to the nearest thousands.
Kuna vitabu vipya vya form 1 ambavyo vimenichanganya. Wanadai kuwa,'if the digit immediately to the right of the required place value is exactly 5,the required place value increases by 1 when it is odd,but remains unchanged when it is even,and replace the digits to the right of the required place value with zeros'. Msaada tafadhali,nilikuwa nafundisha nikakwama kwa muda,kwa sababu vitabu vingine vinasema,ile namba ikishafika 5 tu,unaongeza 1 kwenye namba husika.

Mkuu kilichoandikwa ndio sahihi

Mkuu kilichoandikwa ndio sahihi

kipi kati ya hivyo viwili vilivyoandikwa kwenye vitabu tofauti?

 

[Tewe]

To increase by one, rhs number must be odd

 

[Tewe]

Kumbuka hiyo ni advanced mathematics, kwenye shule za kata usini-quot tafadhali

 

[Msafiri Kasian]

Nashukuru! Ila hii imekuwa introduced o level pia. Ndo nafundisha approximations.

 

[Nyakageni]

Nadhani wamekosea! Ni kitabu gani mkuu? Oxford?

Nadhani wamekosea! Ni kitabu gani mkuu? Oxford?

Ipo katika vitabu hivi;
1.Maths For Secondary Schools Form 1 Student's Book-Oxyford University Press(T) Ltd(first edition 2009).
2.Secondary Basic Maths-Tanzania Institute of Education(First print-2009).
Vyote hivi viwili vimeandika hivyo.

Alafu pia,hii concept imenisababishia maswali mengi sana darasani mf. How do I round off 0.07052 to the nearest thousandth.?

 

[Msafiri Kasian]

Wadau naombeni ufafanuzi zaidi kuhusu hii concept.

 

[cpt]

hyo concept ipo cku nyingi sana tena ktk vitabu vya shule ya msingi ila kutokana na ugumu wa kuwaelekeza wtt walimu wengi waikwepa kufundisha kwa kuzingatia odd na even number!

Aha! Kwa hiyo kumbe ipo tokea shule za msingi? Sasa mimi najiuliza,hawa watoto watakapo ulizwa swali kama hli kwenye mtihani wa nje(mf. Wa taifa) itakuwaje? Wasahishaji watatumia concept ipi?

 

[cpt]

Hili lipo wazi sema walimu wng wanalikwepa!utata upo katika tarakimu aushi(significant figures) hapo ndo balaa coz hazipo universal!

Unachoongelea hapa ni rounding wakati kuna tie (ngoma draw), yaani namba ya kushoto imekuwa 5, kwa mfano 33,500 round to thousands.

Kuna njia nyingi za kuvunja hii draw.
Round half up -> Unaround kwenda juu (Njia ambayo ndo most common)
Round half Down -> Unaround kwenda chini

Round half to even ->(Njia iliyoandikwa kwenye kitabu chako)

Kuna njia zengine kadhaa zote ni sahihi, inategemea mmeamua kutumia standard ipi, naona kwa bongo wameamua kubadili kwenda hiyo ya half to even badala ya round half to up kama tulivyosoma sisi.

Unaweza kuziona njia zote Wikipedia Rounding - Wikipedia, the free encyclopedia

Kuhusu swali lako la rounding decimal to thousands jibu litakuwa zero. 00|000.07052

Hii ni basic mathematics na si advanced.

Sasa kijana hapo tatizo nini? si namba imeshaongezeka zaidi ya hiyo 4 ya maelfu, kuna 589 mbele yake na hakuna sifuri. Maelfu hapo ni kwenye hiyo 4 na si kwenye tano, kwenye tano ni mamia na yamezidi zaidi ya tano.

Kwa hiyo hapo bila mjadala unaongeza moja yaani inakuwa 325,000
