In order to prove the sentence 2/5 + 4/10, a partitioned model could be used. Here, 2/5 equates to 4 out of 10 parts and 4/10 equates to 4 out of 10 parts. Adding these provides a total of 8 out of 10 parts, thereby proving the sentence is true.
To prove the number sentence 2/5 + 4/10 is true using a partitioned model, you need to start by understanding that fraction addition involves just combining the fractions. If you partitioned a model into 10 equal parts representing 1 whole, 2/5 would be 4 parts and 4/10 would be 4 parts. Adding these together 4parts (being 2/5) + 4parts (being 4/10) makes 8 parts. Since 1 whole is made up of 10 parts, 8 parts equate to 8/10 or 0.8. Therefore, 2/5 + 4/10 = 0.8 or 8/10 validating the sentence as true.
