a) Apple after sold 60% = 3 × 40% = 1.2
New ratio A : O
= 1.2 : 10
= 12 : 100
= 3 : 25
New ratio A : O
= 1.2 : 10
= 12 : 100
= 3 : 25
Thank you
b) answer 400. You do the working.
May I ask why can’t I simplify it by dividing? Instead I have to change 1.2 to 12?
Can also..
You will get
0.3 : 2.5
But ratio need to be a whole number.
In the end, answer need to multiply to 3:25
