Look at grid A again. Is the grid coloured ―
(a) $\frac{1}{2} \mathrm{blue}, \frac{1}{2} \mathrm{white}?$

(b) $\frac{2}{4} \mathrm{blue}, \frac{2}{4} \mathrm{white}?$

(c) $\frac{3}{8} \mathrm{blue}, \frac{5}{8} \mathrm{white}?$

(d) $\frac{4}{8} \mathrm{blue}, \frac{4}{8} \mathrm{white}?$

Mark (✕) on the wrong answer.

Total number of squares in grid A                = 16
Number of squares that are blue-coloured   = 8
Number of squares that are white-coloured = 8

Fraction of grid A that is blue-coloured   = $\frac{1}{2}$
Fraction of grid A that is white-coloured = $\frac{1}{2}$

So, $\frac{1}{2}$ of the grid A is blue and $\frac{1}{2}$ of the grid A is white.

$\frac{1}{2}=\frac{2}{4}=\frac{4}{8}$
 

a) $\frac{1}{2}$ blue, $\frac{1}{2}$ white	b) $\frac{2}{4}$blue, $\frac{2}{4}$ white
c) $\frac{3}{8}$ blue, $\frac{5}{8}$ white  (×)	d) $\frac{4}{8}$ blue, $\frac{4}{8}$ white
