First answer:
If you look carefully to the measures of the three triangles that are the ramps of the exercise, you will notice they are similar after comparing them.
• Ratio of Ramp 1 = 2/3
,
• Ratio of Ramp 2 = 4/6
,
• Ratio of Ramp 3 = 6/9
Second answer
The information is given on the image and we can calculate the missing measures for make a smooth slide:
• Ramp 1 - Base 10 - Height 12
,
• Ramp 2 - Base 15 - Height 18
,
• Ramp 3 - Base 30 - Height 36
We used the ratio 2/3 for answering the first question, now we have the ratio
5/6, as follows:
• Ramp 1 - 5/6 * 2/2 = 10/12
,
• Ramp 2 - 5/6 * 3/3 = 15/18
,
• Ramp 3 - 5/6 * 6/6 = 30/36
