3. Kom ons kyk nou wat gebeur wanneer ons enige getal deur 0 deel. Werk weer saam met ’n maat en doen die volgende met behulp van jou sakrekenaar:

3.1 6 ÷ 0 = ................................... 3.2 38 ÷ 0 = ..............................

3.3 438 ÷ 0 = ............................... 3.4 1 679 ÷ 0 = .........................

  • 63 827 ÷ 0 = .........................

4. Waarom gee die sakrekenaar hierdie antwoorde?

Onthou jy nog?

Deling deur 0 is nie toelaatbaar nie. Ons sê dit is ongedefinieer.

KOPKRAPPERS!

Ek dink aan ’n getal. As ek 3 aftrek en die getal deur 6 deel, is die kwosiënt 7.

Wat is die getal? ..................

Ek dink aan ’n getal. As ek dit halveer en dan deur 12 deel, is die kwosiënt 9.

Wat is die getal? ..................

Aktiwiteit 4:

Om verskillende maniere van skryf in verskillende kulture te beskryf en te illustreer [lu 1.2]

Het jy geweet?

Die Chinese skryf óf van bo na onder óf van links na regs. Van hulle syfers lyk so:

1.

2.

3.

4.

5.

6.

7.

8.

9.

10.

100.

1.1 Kan jy die volgende in Chinees neerskryf? Gee dan die antwoord in ons getallestelsel.

a) 10 ÷ 1 = .........................................................................................................
b) 100 ÷ 10 = ...........................................................................................................
c) 9 ÷ 3 = ..........................................................................................................
d) 100 ÷ 4 = ...........................................................................................................
e) 100 ÷ 5 = ...........................................................................................................
f) 100 ÷ 7 = ............................................................................................................

Deling deur 10, 100 en 1 000

Aktiwiteit 5:

Om waargenome patrone en reëls in eie woorde te beskryf [lu 2.2]

1. Sekere reëls in Wiskunde maak dit vir ons maklik om vinnig ‘n antwoord te bereken. Ons moet egter eers die reël kan “raaksien” of “aflei” voordat ons dit kan toepas. Werk saam met ’n maat en voltooi die volgende tabel:

Getal 20 50 90 120 360 1 470 2 560 14 380 26 520
÷ 10 ............ ............ ............ ............ ............ ............ ............ ............ ............

Wat merk julle op as julle na die antwoorde kyk?

2. Voltooi ook die volgende:

Getal 300 800 1 200 2 600 14 700 32 500
÷ 100 ................. ................. ................. ................. ................. .................

Kan julle ’n reël vir deel deur 100 neerskryf?

3. Kan julle ook die antwoorde van die volgende neerskryf?

Getal 5 000 7 000 13 000 45 000 126 000 382 000
÷ 1 000 .................. .................. .................. .................. .................. ..................

Wat gebeur wanneer ons deur 1 000 deel?

Deling deur veelvoude van 10 en 100:

Aktiwiteit 6:

Om te bereken deur geselekteerde bewerkings te gebruik ]lu 1.8.4]

1. Jy het nou reëls ontdek vir deling deur 10, 100 en 1 000. Kom ons kyk nou na deling deur veelvoude van 10 en 100. Werk saam met ’n maat deur die volgende berekenings:

explain if oxygen is necessary for photosynthesis
Allice Reply
Yes, the plant does need oxygen. The plant uses oxygen, water, light, and produced food. The plant use process called photosynthesis.
MG
By using the energy of sunlight, plants convert carbon dioxide and water into carbohydrates and oxygen by photosynthesis. This happens during the day and sunlight is needed.
NOBLE
no. it s a product of the process
Anastasiya
yet still is it needed?
NOBLE
no. The reaction is: 6CO2+6H20+ solar energy =C6H12O6(glucose)+602. The plant requires Carbon dioxyde, light, and water Only, and produces glucose and oxygen( which is a waste).

anabolism and catabolism
Sani Reply
Anabolism refers to the process in methabolism in which complex molecules are formed "built" and requires energy to happen. Catabolism is the opposite process: complex molecules are deconstructed releasing energy, such as during glicolysis.
