4% means 4/100, and to find 4% of 263, you would multiply 4% with 263, which would make an equation like this: 4/100 x 263. You should know that you divide first, so now your equation is: 0.04 x 263. All you have to do now is multiply those two numbers and you get the sales tax, which is 10.52 or 10.5
The smaller side is 4 units going from point (2,2) to point (6,6) while the biger side is 8 units long going from point (6,6) to point (14,14). So 4 is 1/2 of 8 therefore there is a 1:2 ratio because of 4:8
