If you were to make a line graph which two numbers would be 3.275 be in between if you are trying to round it to the nearest whole number, tenth, and hundredth.

Whole number would be 3, so the middle would be 1.5
Nearest tenth would be 3.3, so the middle would be 1.65
Nearest hundredth would be 3.28, so the middle would be 1.64
(I'm not sure if that's what you meant)

If jon had $4.00 then takes away $2.25, then he should have $1.75 left. $4.00 - $2.25 = $1.75 hope this ; )
