Hi Charles!
Dankie vir jou vrae (",)
As ek na die antwoorde kyk, lyk dit of jy die vraag verkeerd verstaan het...jy kan hier click om weer die video oor verdeling met verhouding te kyk.

Verdeel 2.5 in verhouding 2:3

$table row cell 2 colon 3 end cell row cell 2 plus 3 equals 5 end cell row cell fraction numerator 2.5 over denominator 1 end fraction cross times 2 over 5 equals 1 end cell row cell fraction numerator 2.5 over denominator 1 end fraction cross times 3 over 5 equals 1.5 end cell end table 2.5 space v text erdeel in die verhouding end text 2 colon 3 space is space bold 1 bold colon bold 1 bold. bold 5 T O E T S colon space 1 plus 1.5 equals 2.5 space$

Verdeel 112 in verhouding 4:3

$table row cell 4 colon 3 end cell row cell 4 plus 3 equals 7 end cell row cell 112 over 1 cross times 4 over 7 equals 64 end cell row cell 112 over 1 cross times 3 over 7 equals 48 end cell end table table attributes columnalign left end attributes row cell 112 space verdeel space in space die space verhouding space 4 colon 3 space is space bold 64 bold colon bold 48 end cell row blank row cell TOETS colon 64 plus 48 equals 112 end cell end table$

As ons getalle vermeeerder/verminder dan sit ons die twee verhoudings op mekaar - soos wat jy gedoen het.

Maar as ons getalle in verhouding moet verdeel, dan plus ons eers die verhoudings bymekaar om 'n nuwe noemer te kry
