Simple method :
First, find the 8 % of 8550 it will be = 684.
Next, find the 9% of 5700 it will be = 513.
Last step 513/684 * 100 = 75%.

Simple method. You get 57/76 which is further indivisible by single no. So now calculate as(5+7)/(7+6) which gives,
12/13 repeat one more time (1+2)/(1+3) equals 3/4 i.e 75%.
12/13 repeat one more time (1+2)/(1+3) equals 3/4 i.e 75%.

9*5700/8*8550 simplification for this.
Step 1: 9% of 5700 = (10%-1%) of 5700 it becomes (10% of 5700-1% of 5700).
= 570-57 = 513.
Step 2: 8% of 8550 = (10%-2%) of 8550.
It becomes (10% of 8550 - 2% of 8550).
= 855+171 (i.e 41% of 8550 is 85.5. So 2% of 2500 is 85.5+85.5 = 171.0).
Now last step is 513/684 = 0.75 (i.e 684) 51300 (0.75).
It becomes 51300.
Final step 0.75*100 = 75%.
Step 1: 9% of 5700 = (10%-1%) of 5700 it becomes (10% of 5700-1% of 5700).
= 570-57 = 513.
Step 2: 8% of 8550 = (10%-2%) of 8550.
It becomes (10% of 8550 - 2% of 8550).
= 855+171 (i.e 41% of 8550 is 85.5. So 2% of 2500 is 85.5+85.5 = 171.0).
Now last step is 513/684 = 0.75 (i.e 684) 51300 (0.75).
It becomes 51300.
Final step 0.75*100 = 75%.

(9% of 5700)/(8% of 8550)*100 = ((9/100)*5700)/((8/100)*8550)*100.
= (9*5700)/(8*8550)*100 = 0.75*100 = 75%
= (9*5700)/(8*8550)*100 = 0.75*100 = 75%

9% of 5700 becomes 9% x 5700. But, 8% of 8550 remains the same. Why?

9% of 5700 - 8%of 8550*100 = 75%.

Step 1:
9% of 5700.
= (10%-1%) of 5700.
= (10% of 5700) - (1% of 5700).
= ((10/100) *5700) - ( (1/100) *5700).
= 570-57.
= 513.
Step 2:
Similarly, 8% of 8550 = 684.
Step 3:
Finally, 513/684 = 0.75.
As we need percentage, multiply with 100 you will get 0.75*100 = 75%.
9% of 5700.
= (10%-1%) of 5700.
= (10% of 5700) - (1% of 5700).
= ((10/100) *5700) - ( (1/100) *5700).
= 570-57.
= 513.
Step 2:
Similarly, 8% of 8550 = 684.
Step 3:
Finally, 513/684 = 0.75.
As we need percentage, multiply with 100 you will get 0.75*100 = 75%.
