Question

name the property used in each of the following: -1/3 + (2/5+2/3) = (-1/3+2/5)+2/3​

Answer 1

Answer:

$\frac{ - 1}{3} + ( \frac{2}{5} + \frac{2 }{3}) = ( - \frac{1}{3} + \frac{2}{5} ) + \frac{2}{3} \\ \frac{ - 1}{3} + \frac{16}{15} = \frac{5}{15} + \frac{2}{3} \\ \frac{11}{15} = \frac{15}{15}$

this is not equal
