This can be done algebraically:
300*x=330 Where x is the multiplier
Therefore x=330/300=1.1
To find a percentage of a number you multiply by the percentage divided by 100.
So 330 is 110% of 300, which is an increase of 10%.
8.8 because you need to multiply 1.68 by 10 which is 16.8-8=8.8
(57-32)➗5.5 =x
The problem is just flipped.
Cy + b ÷a
Hope this helps :)
