Question

Use commutative property to solve
2/5 + 7/3 + -4/5 +-1/3

please solve asap...

Answer 1

Answer:

$= \frac{8}{5}$

Step by step solutions:

$= \frac{2}{5} + \frac{7}{3} + ( - \frac{4}{5} ) + ( - \frac{1}{3} )$

$= \frac{2}{5} - \frac{4}{5} + \frac{7}{3} - \frac{1}{3}$

$= \frac{ - 2}{5} + \frac{6}{3}$

$= \frac{ - 2}{5} + 2$

$= \frac{ - 2 + 10}{5}$

$= \frac{8}{5}$

Answer 2

Question:-

Use commutative property

$\frac{2}{5} + \frac{7}{3} + \frac{ - 4}{5} + \frac{ - 1}{3}$

Solution:-

Commutative property a+b = b+a

So, it can be written as

$\frac{2}{5} + \frac{ - 4}{5} + \frac{7}{3} + \frac{ - 1}{3}$

$\frac{2 + ( - 4)}{5} + \frac{7 + ( - 1)}{3}$

$\frac{ - 2}{5} + \frac{6}{3}$

$\frac{ - 2}{5} + 2$

$\frac{ - 2 + 10}{5}$

$\frac{ - 8}{5}$

Final answer:-

$\frac{ - 8}{5}$
