Question

verify that please.....

Answer 1

$\frac{3}{5} + ( \frac{ - 1}{7} ) = ( \frac{ - 1}{7} ) + \frac{3}{5} \\ lhs = \frac{3}{5} - \frac{1}{7} \\ \frac{21 - 5}{35} \\ \frac{16}{35} \\ rhs = \frac{ - 1}{7} + \frac{3}{5} \\ = \frac{ - 5 + 21}{35} \\ = \frac{16}{35} \\ lhs = rhs$

Answer 2

This can be verified by using Commutative Property under addition.

3/5 + [-1/7] = [-1/7] + 3/5
3/5-1/7 = -1/7+3/5. { Solving the brackets }
21/35 - 5/35 = -5/35 + 21/35. { Taking LCM }
16/35 = 16/35

• Hence proved
