Keep, change, flip
Example: 3/4 divided by 6/8
Step 1: keep 3/4
Step two: change the division sign to a multiplication sign
Step 3: flip 6/8 and make it 8/6
Step 4: multiply it, then that’s your answer to the division problem
The first one is x^2+2x+2
the second one is x^2+4
the last one is x^2-4x+8
We are given
The current exchange rate is 2 guilders for every 3 florins
so,
2 guilders = 3 florins
now, we can find for 1 guilders
so, we get
now, we can multiply both sides by 17
now, we can simplify it
so, option-A........Answer

I know this because 40% out of 100 and x/25 are how many students will get it.
#1 is A because the equation is pi x diameter which would be 18.84
