Attached is the solution
6/30 and 6/10 are not multiples of 3/10 because you cant take 3/10 and multiply both the numerator and the denominator by one number and get 6/30 or 6/10 but a multiple would be like 6/20, 18/40, 30/100 and so on.
Missing number is 46 so just shade 46 squares in the grid
Well when you multiply 32 times 5 you should end up with 160. Unless you multiplied the answer so wrong
