HELP PLEASE !!!

For 121 you only really need to consider a quarter of the flag (since the fraction of the quarter will be the same as for the entire flag)

Then if you divide that quarter into quarters, you'll see just how much the blue diamond fills up


For 128, the hints tell you that the numbers 5 and 7 are not used and that each line of three numbers multiply to 72

This means that one of the numbers must be 1, which in turn means that there must be a line with the numbers 1, 8 and 9

As 1 can't be used again (there can't be another line of 1, 8 and 9) and no two other numbers multiple to 9, that means that 9 must be used as part of another line where you need to find two numbers that multiply to 8

Keep going with this logic and you'll get there

For puzzle 128 try putting the numbers 1,9 and 8 in either of the up and down sides, but make sure that 9 is in the middle of that line. For puzzle 121 - if you take the box and divide it in fourths and then each 1/4 into 1/4 again. Now you have 16 squares, each one of the center squares are divided in half with blue and yellow, from here imagine putting one of the blue pieces into the other half where the yellow is. How many squares of the 16 would now be totally blue, put it into fraction and bring down to the smallest form. If you need further help - email me at [email protected]
