Multiply 1.5 and 1 as fractions

So 1.5 means 1 and 1/2 or 2/2+1/2=3/2

and 1=x/x where x=x so 1 could be 1/1 or 3/3 or 2342/2432 and so on
for simplicity just use 1/1

to multiply fractions just multiply the top numbers by the top numbers and the bottom numbers with the bottom numbers so 
3/2 times 1/1=(1 times 3)/(1 times 2) or the same thing since anything times 1 is the same thing so the answer is 3/2 or 1 and 1/2

Add up all the sides
