Given the subtraction problem;
2.25-(-0.25)
First we will need to open up the parenthesis by multiplying the signs. product of two negative signs will result in a positive. Hence the equation becomes;
= 2.25+0.25
Convert to fraction;
= 225/100 + 25/100
Find the LCM
= (225+25)/100
= 250/100
= 2.50
Hence the difference of both values on the number line is 2.5
