Evaluate the following and write the answer as a decimal 6 and 5/8 + 2 and 1/2

65/8 +2  1/2=53/8+2 1/2=53/8+5/2=73/8=9 1/2 or 9.125hope this tell me if i am wrong 

If i think this is what your asking, he should look at the grams or pounds/ounces and compare the to their cost then max can identify which one is proportional and which is not ( i think xd)

(x) - (y) = (1 + 4i)

(3 + 6i) - (2 + 2i) = (1 + 4i)
