Question

using commutativity and associativity of addition of rational numbers, express the following as rational number. 5/2+-3/7+1/2+4/7​

Answer 1

Answer:

22/7 = 3$\frac{1}{7}$

Step-by-step explanation:

5/2+-3/7+1/2+4/7​

= (5/2 + 1/2) + (-3/7 + 4/7)

= 3(6/2) + 1/7

= 3/1 + 1/7

= $\left \ {{3*7} \atop {1*7}} \right.$ + 1/7

= 21/7 + 1/7

= 22/7 = 3$\frac{1}{7}$

This is done by associativity of addition of rational numbers property.
