Upper primary school mathematics question UPQ121
In the figure below not drawn to scale, 2/11 of X overlaps with 1/4 of Y. Express the ratio of the unshaded area of X to the unshaded area of Y in its simplest form.
2/11 of X overlaps with 1/4 of Y
2/11 of X equivalent to 1/4 = 2/8 of Y
So in ratio, X : Y : Shaded = 11 : 8 : 2
X unshaded : Y unshaded = 9 : 6 = 3 : 2
