sstrike's answer to Mani's Primary 6 Maths Percentage Singapore question.
Tks, for section b, why multiply by 5?
$6.8 → not a whole number
$2 → whole number & even number
0.8 = ⅘
0.8×5 = 4 → whole number
5 × $6.8 = $34 → whole number & even number
So that
34 is the common number for
6.8 & 2
$2 → whole number & even number
0.8 = ⅘
0.8×5 = 4 → whole number
5 × $6.8 = $34 → whole number & even number
So that
34 is the common number for
6.8 & 2
