May I know why 2/3 has to change to 4/6? Can we just take denominator 3+3=6 as total of red & blue stickers? Thank you
“In the end, she has 1/4 of stickers”
12 can be divided by 4, but 6 cannot be divided by 4 without leaving a remainder.
So 2/3 is changed to 4/6 to make things easier.
If you had directly gone into writing the total as 6 units, you'll still have to change the denominator to 12 (or other numbers exactly divisible by 4) later on in the working so that it can be divided exactly.
So it's a matter of changing it first or later
