12. The question is asking to convert 50 meters into decimeters.
1 meter = 10 decimeters
50 meters = x decimeters
Since the 1 was multiplied by 50 to get from 1 meter to 50 meters, multiply the 10 by 50 to make this equation equivalent.
10 • 50 = 500
So the race is 50 decimeters long.
13. The question says that the blanket Alexis is knitting is going to be 2 meters long. Every 2 decimeters in those 2 meters, the colors will change. The question wants to know how many stripes there will be due to these color changes.
1 meter = 10 decimeters
2 meters = 20 decimeters
20 decimeters (total) ÷ 2 decimeters (when the color changes each time)
20 ÷ 2 = 10
There will be 10 colors in the blanket.
You can check this by making a small diagram:
2 decimeters - 1 total stripe (total so far: 0.2 meters)
2 more decimeters - 2 total stripes (total so far: 0.4 meters)
2 more decimeters - 3 total stripes (total so far: 0.6 meters)
2 more decimeters - 4 total stripes (total so far: 0.8 meters)
2 more decimeters - 5 total stripes (total so far: 1 meters)
2 more decimeters - 6 total stripes (total so far: 1.2 meters)
2 more decimeters - 7 total stripes (total so far: 1.4 meters)
2 more decimeters - 8 total stripes (total so far: 1.6 meters)
2 more decimeters - 9 total stripes (total so far: 1.8 meters)
2 more decimeters - 10 total stripes (total so far: 2 meters)
After 2 meters of the yarn color changing every 2 decimeters, the total stripes in the end is 10.
Hope this helps! :)
