The equation looks like this:
%283%2F4%291.5=R
%283%2A1.5%29%2F4=RMultiply 3 by 1.5, you'll get 4.5
4.5%2F4=RDivide 4.5 by 4 to get 1.125
R=1.125
or you could do everything in fraction form. Convert 1.5 to 3%2F2
%283%2F4%29%283%2F2%29=R
%283%2A3%29%2F%282%2A4%29=R
R=9%2F8
Since 9%2F8=1.125 the equation works. So R=9%2F8 or R=1.125
