Ok, here's a trick: If you're converting a smaller unit to a bigger unit in metric system, you divide by 10. When you are trying to convert a bigger unit to a smaller unit, multiply by 10. Decimeters are 1/10 of a meter, so you are going to multiply 2 by 10 because you are converting a bigger unit to a smaller unit, in which you get 20.
So your answer is 20 decimeters.

Answer:
- 8/25 = 32/100
- 7/20 = 35/100
Step-by-step explanation:
25 and 20 have a least common multiple of 100, so that is your least common denominator.
8/25 = (8·4)/(25·4) = 32/100
7/20 = (7·5)/(20·5) = 35/100
