Swali la shule ya msingi nimeulizwa na binti yangu nikachemka.
Naombeni msaada wenu.
Swali.
The average of three numbers is 48.The average of two of them is 45.Find the third number.

The average of three numbers is 48.The average of two of them is 45.Find the third number.

sum of the two numbers: 2*45 = 90
sum of the three numbers: 3*48 = 144


-----
Value of the third number: 144-90 = 54

Hongera sana.
Sikufikiria hivi hata kidogo.

Let
First No=a
Second No=b
Third No=c

Requestion No 1
(a+b+c)/3=48
a+b+c=144..........(i

Equestion No 2
(a+b)/2=45
a+b=90..................(ii)

Come to the equestion No 1 and substitute Requestion No 2 in No 1

if
a+b+c=144
and a+b= 90

Make substitution

(a+b)+c=144
90+c=144
c=144-90
c=54

Third No = 54

Wanakomaza tu mtoto...

Huwenda hajui mambo madogo ila wanamjaza hili lililomzidi umri.

 

[Kyamtwala]

((x+y+z)/3=48)-((x+y)/2=45)

(48x3)-(45x2)

144-90=54

The third number is 54

Hii njia sio sahihi hata kama jib litakuwa sahihi
Kwa maoni yangu

Hiyo njia ni kwa Seniors tu ambao tushapambana na hisabati za kiwango cha juu kabisa, kwa Senior Mathematician siwezi angaika na swali la kitoto ama ilo eti nianze sijui Let Q be the first number na bla bla bla, iyo wanafanya beginner wa mathematics kwa swali kama ilo

Hysee! lengo sio kuonesha useniors lengo ni kuelekeza mwingine aelewe ili awe senior kama wewe

Wewe pia ni genius, ila ukifanya hivyo kwa mwalimu wa mathematics unapata alama chache, walimu sijui tunakwama wapi.

 

[Msafiri Kasian]

Hii njia sio sahihi hata kama jib litakuwa sahihi
Kwa maoni yangu

Hapa ndo tunapofeli walimu wa mathematics, matokeo yake tunaua kabisa vipaji vya watoto tunaowafundisha. Mi nadhani hii soln yake ni sahihi na ni "higher order of thinking" imetumika, na kuna logic ndani yake.

Inatakiwa ifike mahali na sisi walimu na Watanzania kwa ujumla tuthamini na tutambue tuna uwezo tofauti tofauti wa kufikiri, tusibaki tu kukariri yaliyoandikwa kwenye vitabu.

Unaporuhusu njia isiyo sahihi, unaweza badili data za swal kwa concept hiyo hiyo ya swali afu majibu sahihi yasipatikane
Ndo mana kwang mm lazma mtoto anionyeshe logic ya njia yake

 

[Finder]

Kwa nini?

Sababu hapo umetumia data kugues namba unazotafuta
Kwa mfano umeambiwa the sum of two numbers is 90
Wew tyr ukafikir the two numbers ni 45
Jee kama ingekuwa 40 na 50.
So njia sio sahihi ukibadilisha data za swal kwa concept hiyo hiyo hupat jib.
