13/20 because it is 6.5 vs 5/8 being 6.25

13/20 would be the same as 65%. Divide 13 by 20 to get 65%. Then 5/8 would be the same as 62.5%. Divide 5 by 8. The reason I do it this way is because you could spend all day multiplying the fractions to higher numbers and see which is bigger, but converting to other forms is the best to tell. Percentages don't lie. So that means that 13/20 is bigger.

How do you use theorems about triangles to solve problems???

bazaltina [42]

9514 1404 393

Explanation:

Theorems about triangles identify relationships that can be used to formulate equations that can be used in the problem-solving process.

The idea with problem solving is to start with what you know, and make use of the relationships between that and what you don't know in order to find a solution.
