First way to solve:
10%=10/100
10%=0.1
To find 10% of 10, you do 0.1 times 10:
0.1*10=1
Now that you know what 10% of 10 is 1:
10-1=9
Second way to solve:
If you want to decrease 10kg by 10%, it means you want 90% of 10kg because:
100%-10%=90%
Know you also know:
90%=90/100

To find 90% of 10, you do 0.9 times 10:
0.9*10=9
