Question

Find the value of following and verify the closure property under the given operation.
-2/3+5/7​

Answer 1

Step-by-step explanation:

Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants. Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant.

Answer 2

Question:-

Find the value of following and verify the closure property under the given operation.

⟹ -2/3+5/7

Answer:-

closure property: a+b = a+b

$\sf⟹  \frac{ - 2}{3} + \frac{5}{7} = \frac{5}{7} + \frac{ - 2}{3} \\ \sf⟹  \frac{ - 14 + 15}{21} + \frac{15 - 14}{21} \\ \sf⟹  \frac{1}{21} = \frac{1}{21}$

hence proved is satisfies closure property under addition.!

hope this helps.!
