Let's consider that 23.5 is 100% of rainfall.
23.5 ..... 100 %
21.2 ..... x %

If F wasn't unknown cause it cannot be then:
x+2 = 3x+5
-2x = 3
x = -3/2
x+2 = 3x+5
-2x = 3
x = -3/2
x+2=3x-5
3x-5=x+2
3x-x=2+5
2x=7
x=7/2
3x-5=x+2
3x-x=2+5
2x=7
x=7/2

Well this would be 23.000 because you know that you can move a number up when the number next to it is more than 5 and the number 1 is next to the zero that is in the tenths place so that will become zero because it is less than 5.

No. 7/20 is NOT equivalent to 7 hundreds or 7 hundredths.
7 hundreds is 700 in standard form.
7/20 will become a decimal number. It is equal to 0.35
0.35 is not equal to 700.
7 hundredths in decimal form is 0.07
0.35 is still not equal to 0.07.
