Should be 34 + (80 - 26) - 26 = 62 cm

Ribbon A is 80cm shorter than Ribbon B, so the "gap" in Ribbon A is 80cm. I let the blue part of Ribbon A be 1 unit. So the green part of Ribbon A is 1 unit + 34 cm

Here's something to help students remember perpendicular lines!!! If the 2 kittens here were closer together and touching at their heads, they would be a purrrfect example of perpendicular lines!

Hi, Kellyn. Let me give you 2 hints. Hint 1: Draw the model of 6:1. Hint 2: On that model, add 4 to Roy and 16 to Colin. BONUS HINT: Multiply Colin's new model (that is 1 unit + 16) by 4 so that he has the same number of stamps as Roy (that is 6 units + 4). *When both boys have the same stamps, you will be able to find the value of 1 unit. :) Then, with the value of one unit, most of the fog around the problem will have cleared and you will be able to find out how much Roy has in the end. :)
