Inhoud

Aktiwiteit: om probleme in konteks op te los [lu 1.6.1]

As ons vandag iets by ‘n winkel koop, ontvang ons ‘n betaalstrokie daarvoor. Ons moet dit kan verstaan en “lees”, anders sal ons nie kan kontroleer of die bedrag wat ons moet betaal werklik ‘n weerspieëling van ons aankope is nie. Kyk na die volgende voorbeelde.

1. Bestudeer die bogenoemde voorbeelde en beantwoord dan die volgende vrae:

1.1 Wanneer is die aankope gedoen by

Pick ’n Pay? ____________________________________________________

Ranch Meat Centre? _____________________________________________

1.2 Wat kos die biltong per kg? __________________________________

1.3 Hoeveel items is by Pick ’n Pay gekoop? _______________________

1.4 Hoeveel % belasting moes betaal word by

Pick ’n Pay? ____________________________________________________

Ranch Meat Centre? _____________________________________________

1.5 Hoe (waarmee) het die klant betaal by

Pick ’n Pay? ___________________________________________________

Ranch Meat Centre? _____________________________________________

1.6 Wie was die kassier by Ranch Meat Centre? __________________________

1.7 Watter bedrag het die klant aan haar gegee? _____________________________

1.8 Hoe laat is die aankope gedoen by

Pick ’n Pay? ____________________________________________________

Ranch Meat Centre? _____________________________________________

1.9 As jou aankope nie met die strokie ooreenstem nie, hoe sal jy weet watter kassier het jou by Pick ’n Pay gehelp as jy nie kan onthou hoe hy / sy lyk nie?

1.10 Wat beteken die * langs ’n paar van die bedrae op die Pick ’n Pay strokie?

Onthou jy nog?

Verduidelik aan ’n maat hoe ons afrond tot die naaste 10, 100 en 1 000.

** Kan jy verduidelik hoe ons sal afrond tot die naaste 10 000?

2. Wanneer ons inkopies doen, kan ons deur te skat tot die naaste rand bepaal of ons genoeg geld sal hê om te betaal.

Kyk na die volgende strokie. Rond af tot die naaste rand en skat so hoeveel jy vir jou inkopies moet betaal.

1 liter hoenderstukke

2 g Coke

410 ml Surfmaid ertjies

200 ml Niknaks

3.4 As jy met ’n R100-noot betaal, hoeveel kleingeld sal jy kry?

_____________________________________________________________________

Onthou jy nog?

Jou sakrekenaar het ’n geheue wat jy kan gebruik om berekeninge waarin meer as een bewerking voorkom, korrek te doen.

M+ : stel die sakrekenaar in staat om die antwoord te bêre of te memoriseer

MR / RCM : dié sleutels word gedruk as jy al die gememori­seerde antwoorde wil oproep.

Bv.: (347 219 + 34 987) + (296 553 + 1 897 320)Druk 347 219 + 34 987 = M+ Druk dan 296 553 + 1 897 320 = M+ Druk dan MR / RCM

explain assimilatory nitrate reduction
Esinniobiwa Reply
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
